Great questions!
Ryo and Anna: Yes, biography at beginning of book and book itself can be listed as separate references. A few terms of vocabulary listed at the end may be your choice (if there are particularly difficult terms), but not absolutely required for book report.
Anna: It would not be a crime if the book report ran to four pages but note that you don't have to utilize all the research ideas I gave you, just the ones that seem to be the most interesting . . .
