Screw NoX. If you want some pre-workout energy, have some coffee or a caffeine pill. That's the 'energy boost' that's in there anyway, caffeine. And the arginine in it is pretty well useless pre-workout.

All you really need to get going: protein powder (I suggest whey isolate but really any decent protein will do). Multivitamins. And fish oils.

If you're a newbie to lifting, ride that newbie effect while you can. You'll make killer gains for a while. Then when you're newbie gains start to wear off, worry more about possibly using some additional supplementation.
