You probably want to combine zombie and Guards parts.
This is a very good suggestion. Not only should it cut down on the number of zombie regiment boxes you'd need to buy (should only need one, in conjuction with Cadian bits), but you can always use them just as regular old traitor imperial guard later on depending on how GW changes things.

I'm planning on, since I already have the Cadians, going with a shooty section or two of Traitors. Not a bad plan. My buddy has shown quite often that massed flashlights can put a hurting on just about anything in a d6 based system.

The Zombies/Mutants are going to be purely melee. A beautiful, howling mass of nine-point melee making mutants. One suggestion I might make, is to give at least some of them lasguns in some way shape or form if you are doing combined zombie/cadian figures. Even if they are just strapped to their backs, or wielded backwards like clubs, it'll make them easier to mix in with the rest of your cadians to act as just 'normal' traitors should you decide to use them that way.
As for how the army works, that's sort of up to you as it can be a relatively flexible mix of Chaos Marine and Imperial Guard elements. You can bring in some of the big guns that the Guard has (although not nearly as many), while getting some of the rock hard units that Chaos Marines have to offer. Plus, you get cheap HQ characters that can be attached to your massed shooty units of traitors to buff their leadership.
How the army
looks is even more flexible. As Illpazzo has shown with his Skaveny cult, as long as you have an idea and represent things enough that you're opponent knows what he is shooting at, you're pretty much free to make them look any way you want.
Here's a rough overview of my current Slaaneshi L&tD cult, with some even rougher pictures of the models in progress (this is a low priority project for me, and work/school don't help with that).
HQArch-Heretic and RetinueChaos Lieutenant
Chaos Sorceror
10 Castrati (Chosen Chaos Space Marines)
Marks of Slaanesh
Infiltrate Veteran Skill
Sonic Blasters/Blastmasters
Icon
One of my main shooty units, who can at least handle themselves respectably in CC (as well as any shooty Marine/Chaos Marine at least). I went for the Infiltrate skill to get these guys up front and hopefully into a covered position early in the game so they can put all the firepower dice they can dish out to good use. The Heretic and his Sorceror are kitted out for more H2H oomph in case that's where the unit ends up.
For models, I'm being a tad lazy and using my old, unmodified Fabius Bile for the Arch-Heretic. Actually, this entire army is an excercise in seeing if I could build a suitably themed army out of bits and peices I had lying around. I wanted to spend as little as possible on this force, as I started it right after the last bit of major rules changes/price increases and I was a bit annoyed at GW in general. The Sorceror is an older Fantasy Slaaneshi champion I had lying around, and the Castrati (very much in progress still, hence no photo) are CSM bodies with Dark Eldar legs and arms, and custom built sonic weapons.

Choir Master of the Castrati (Chaos Sorceror)
Aspiring ChampionsTwo bare-bones Aspiring Champions from the L&tD list. These are attached to the traitor shooty units to bump up their leadership, and provide a small bit of help should they get overrun in H2H.
ElitesBig MutiesOld school Chaos Minotaurs, with an equally old Keeper of Secrets as the Big Boss. One of my main CC units, I chose not to 'upgrade' them to the crappy firearms that are available to them. These guys are basically your equivalent to Ogryns, and share many of the same benefits, good tougness, multiple wounds (power weapons? pffft...who cares) and the ability to put out a good beatdown.
Big Muties
Mounted DaemonettesSuper-fast daemonic Genestealers you say? Sign me up! Yes they need to be summoned onto the board, but that's why I have a decent smattering of icons througout the army, including in my infiltrating units.
Model-wise, these are the older, much crappier versions of the mounted daemonettes, but it's what I had lying about, and the butch appearance with all the bondage gear fits the rest of the army, so I'm not that concerned with it.
Daemonettes
TroopsTraitors15 Traitors
Lasguns
Heavy Stubber
Autocannon
Icon Bearer
Two maximium sized units of Traitors for shooting support, these guys are old plastic Goliaths that almost no one wants, so they were easy and cheap to acquire in bulk.
Traitors w/ Aspiring Champion
Bueno's Boys (Infiltraitors)Agitator w/Plasma pistol
Laspistols/CC weapons
Icon Bearer
Since this unit is only 10 men, and is lead by an Agitator instead of an Aspiring Champion, their leadership is reduced, but they may Infiltrate. Their main goal in life is to get as close to the enemy lines as possible and hopefully not die long enough for the Daemonettes to be summoned through their icon. They are kitted out for H2H, partially because that's what I had left for weapons, and partially because of the run and gun nature that the pistols give them, and the fact that if they do survive, they can hopefully throw a few dice into a mixed combat with the Daemonettes or anyone else nearby in CC.

Melta Bombs
Never underestimate the ability of a crack suicide squad of steroid abusing clones on greased pigs going allah ackbar on your opponents Land Raider to discombobulate his strategy. Plus, much like Bueno's Boys, if they survive, they are good grist for the CC mill.
Rough Riders
Traitor Recon (Sentinel Squadron)3 Sentinels w/Lascannons
With a BS of 3 these guys don't actually make that great of an Anti-Tank unit, but they do make a damn good distraction. And they usually get off at least 2 rounds of shooting, so hopefully they inflict some damage before being turned into smoking wrecks.
These particular Seninels are the older (not the really old egg shaped ones) metal Sentinels that a buddy of mine decided didn't fit in his Guard army anymore, so he let me have them. A few bits from an IG Anti-tank sqaud later, and they've become phallo-gunned mechanical approximations of Steeds of Slaanesh.
Traitor Recon (Sentinels)
Heavy SupportLong Thom (Traitor Leman Russ)Battle Cannon
3 Heavy Bolters
Heavy Stubber
Extra Armor
I tend to agree with my friend the Guard player that in a Guard Army, Leman Russes should be kept simple, eschewing the side sponsons and saving those points towards more tanks. As this is the only tank in the force, and because the chassis had been previously assembled for a SW variant Leman Russ (don't remember the name, the one with the twin linked autocanons), I went the opposite route and went for the full load of three heavy bolters. If I have to move and can't use the Battle Cannon, I at least want to be able to throw out a lot of dice. And with BS 3, volume of dice is your friend.
Long Thom (Traitor Leman Russ)
DefilerStock Defiler with no upgrades. This was the last addition to the army, to bring it from an 1850 point Grand Tourney spec to an even 2000 points. As such I didn't have any room left for upgrades. But it's really here just to provide another pie plate to lob around, and to be an even bigger distraction than the Sentinels. Keeping it at 150ish points also allows me to swap either this or other simliarly priced units out for a tourney list, depending on what I think I might need.
I picked this Defiler up for $15 off of
Bartertown. It was already assembled, mising a few minor pieces like the Heavy Flamer and had the start of a paint job on it, but it was damn cheap. A lot of cutting, splicing and swearing later, my cult has the animatronic dark god they deserve.
