I may be a day late and a dollar short on this, but what the hell? Sorry if this sounds vague, but you really do need to narrow your focus if you want good advice. I'd suggest taking a quick look here;

Your stats aren't that bad, truth be told, but you're really not going to get far at all if you keep trying to stay well-rounded. RO at the moment heavily favors people who min-max (it won't so much come renewal, but let's not go there.) You really need to do a bit of research, decide what you want out of your Monk and go from there. You mentioned playing with a friend... Maybe considering what that friend is playing and planning to complement him/her can narrow your focus a bit?
You said that you're currently working on your Vit? Honestly, Vit would be the last stat I'd worry about right now (and Luk doesn't count.) You already have more than enough. Besides, from a purely PVM perspective, Vit really doesn't become useful or important as a defensive stat until most character builds are well into their 90s, especially for Monks, since they really aren't expected to do much tanking unless they're Mental Strength builds. And Mental Strength puts your Def at a fixed level anyway, regardless of your Vit.
Personally, I would get Str, Str and more Str. ALL Monk builds need it. You're not going to kill vey much of anything with your Str as low as it is, which means less exp, of course. Most all Monk builds aim for 110-120 with buffs at level 99.
Dex is lovely. I'd recommend no less than 50 with buffs, and probably more depending on your build (since it reduces cast times for G-Fist, Throw Spirit Sphere, etc.) though Dex builds aren't my area of expertise.
Int is nice to have, but remember that YOU ARE NOT A PRIEST. Unless you go for a crazy Int Guillotine Fist build, you're probably always going to have annoyingly slow regen and a fairly small SP reservoir. And Acolyte SP/regen is horrid anyway. My FS Priest went for 99 Int before getting any other stats and he still had to sit constantly when he was an Aco, even when supporting just one other person.
Agi really depends. Agi builds are great to solo and really do well at lower levels, but most Monk build avoid Agi entirely, with the notable exception of combo builds. Again, you have to decide what you want out of your Monk and plan accordingly.
And one last thing to watch out for... Remember that you need Demon Bane 10 and Divine Protection 10 to get the Monk skill Iron Fists, which is a prereq for almost all Monk skills. With your current skill build, if you go job 50, you'll already have to spend 1 Monk skill point to get them both maxed. And you won't have any of the warp tree skills (Ruwach, Warp Portal, Pnuema.)
I can understand where you're coming from when you say you don't have a specific build in mind, but you should at least have a vague idea. At this point it sounds like you don't, and that's really going to hurt you. My Champ is a Str/Agi/Dex combo build, and I never planned out his stats in advance, but I did enough research about combo builds to know which stats were useful and which weren't. I'm sorry if I sound harsh.
