I just finished a 6 month stint with my trainer. While I am not an expert, I have learned A LOT about lifting and how one's body reacts. If you are wanting to gain muscle mass it is important to:
Eat 5-6 smaller meals a day. This helps the body's metabolism and it won't push out your stomach and give you a belly.
Intake of whey protein is important and you should always have a protein shake with whey protein no more than 30 minutes after a workout.
Cassiene (sp?) is a slow releasing protein that is very important as well. You should take a Casseine protein shake before bed. This way your muscles still have access to protein while you rest.
Also, you should wait a couple of hours to eat AFTER a workout as your body will transfer blood to help you digest your food instead of the blood going to the muscles you work out.
Just a few tips I've learned. Good luck!
