Is reading Jech's text on [Set Theory][1] too little, just enough, or overkill to prepare oneself to do independent research in set theory?  This would be my first attempt at doing independent research after taking 5 graduate level math courses and doing well.  If I think I'm interested in Set Theory, and want to get a feel for research, is this the way to proceed?
