From my perspective, since you are already familiar with Eclipse, and assuming you are using netbeans as an IDE, not as a client platform:
- Play with netbeans for an hour. Figure out how to map your day-to-day activities in your previous class onto netbeans (create a project, compile, run, debug)
- Spend some quality time with the tutorials and help at netbeans.org, which will most likely answer 90% of your questions
Sadly, there isn't a great book I've been able to recommend to my folks who use netbeans. It may be worthwhile poking around a bookstore and seeing if you can find one that is closest to the eclipse book that you used (and, presumably, liked).
It also would be worthwhile asking the prof or TA if they have a recommendation. As in any semester long programming class, you are going to be learning a syllabus that is full of the professor's bias, and he may have a book or approach that is most compatible with his classroom approach.
