I can also put alot of useful input coming from a bodybuilding/power lifting family =] Umbrella's advice is very good. a few tips are eat before bed especially a lot of carbs. pasta.. rice.. cottage cheese are some of my favorites. weight gainers before bed are good also. a key body part is legs they are pretty much the true foundation and produce the most growth hormones. squats are my favorite. don't give up even if it gets tough i had to push hard to be where i am today.. as a freshman i was around 110 lbs.. sophomore i jumped to 180ish.. part of that was because i was still growing and the other part is i worked me ass off... i ate around 5000+ calories a day.
