A really great site for all things weight lifting is www.t-nation.com, they have a ridiculous amount of articles on programs, nutrition and the such.
Unfortunately college has made me lazy and I'm just getting back into lifting. 2 summers ago(after my senior year of HS), I was an animal, 6'3 225 lb at around 12% BF and I went the other day to get my BF tested and I was at almost 25%! Luckily, I have nothing to do this summer other than workout and work and I work at our campus rec center, so no excuses about not wanting to drive there or anything of the sort.
DBD, I've never had any good experiences with muscletech(the brand that makes nitro-tech) and try to stay away from it. Just a heads up that you may not be getting your $ out of it.
