Questions / Advice regarding Protein Supps

With my recent weight loss and the start of school I will finally have access to a way above average gym. I want to make the most of it and while I can find plenty of sound, un-biased information about workout routines, it seems more difficult to get sound opinions on protein / crientine supplements...

My diet has nearly no protein in it as I am doing the meal replacement bars. they have approx 32g protein a bar and I eat 3 a day. on the days in between I eat salads with a small meat portion at best...

How much protein do I need to develop muscle but not gain weight? or if one inevitably leads to the other, so be it...

What supps do you guys recommend for protein? what supps do you recommend for recovery?


Thanks for your input in advance fellas...
