Dummitt and Foote suggested above is a great text on the subject and probably the best when it comes to a complete treatment of the theory.
The only complaint one could make is that it's written for mathematicians.
A more appropriate book for "lower level" students (in terms of mathematical maturity) would be John B. Fraleigh's "A First Course In Abstract Algebra".
