Decide if you want to gain muscle or lose fat. The two are entirely different goals.
This piece of advice is garbage. You want to gain muscle to begin with, because muscle takes more energy to maintain, which in turn increases your BMR (Basal metabolic rate.) This is what you want for long term fat burning goodness.
This is an advanced thing, and after 6 months at the gym I'm only getting into it now. Seriously, just track your caloric intake. It's simpler and will give you a feel for the nutrition commitment involved.
Remember, you can't out-exercise your diet. Look at macros after a little practice, but in the mean time, just avoid "simple carbs" high sodium and high fat foods.

Get on a solid muscle-building program. As a beginner, compound lifts will give you the most result. Programs suited for beginners include: Starting Strength, Stronglifts, & All Pros. More can be found online.
This is directly contradictory to the first point made, and agrees 100% with what I said - build muscle. Lean, strength muscle is a great place to start. I started with the Strong lifts 5x5 and have recently progressed to a cutting regime with an IIFYM diet and a Zyzz workout. This is not a place to start, but something I'm experimenting with as summer comes into the late season in Aus.

Ask questions when you need it or if you need a form check. Injuries and lifting go hand in hand if proper form isn't done.
This is dead on. Anybody who's got a physique will usually feel an ego boost if you ask them for help, and if they shun you, well there are plenty of others. The PT's on duty at the gym will usually lend a hand as well. I had a PT spend half an hour with me on my squat form and he wrote it off as promo.
Don't be afraid to ask.

Wipe down equipment after use,
don't sit/text and take up equipment when you're not using it, put equipment and weights back, and be nice.
That's about it~
You will be a hero if you do this. Everybody sits and texts/stretches on or otherwise takes up equipment they aren't using, especially if you're on your rest period between sets. As long as you don't overstay your rest period for a text reply or something.
