I've probably taken too many courses on this and related topics during my undergrad, going from basic group theory to category theory, representation theory, and algebraic geometry. For the uninitiated, a great first book is Fraleigh's text - very down-to-earth and conversational. When you're done with that you can read Dummit/Foote and for those with serious gumption, Lang's classic text. Have to say, it was my favorite subject - clean, elegant, and abstract.
