Bulking Up (Getting Ripped Before School)

Need some advice from the Ootsters. I'm trying to put on some muscle mass before school starts. I wouldn't mind some fat either - just hopefully more muscle than fat. I'm currently going to the Gym 3 times a week and working the arms mostly.

What supplements should I be taking to further enhance this? Any suggestions or past experiences would be extremely helpful. I'm currently 6'2 150 lbs and would like to try and be 160-165 by the end of the month. Is this unreasonable?

Thanks in advance
