Dean,
1. Yes
2. I don't think there is such a book. there a number of good books on EJB (I've got the Ed Roman book, which is a good place to start for people with little or no experience of EJB's). If you want a book to help you pass the exam, I suggest waiting for Kathy's book. It looks like it will do the job comfortably.
