If you plan to collect only the more modern US Mint proof sets, the Guide Book that you've already purchased is about as good as you're going to get â€" it has the most information on these newer sets.
If, however, you plan to venture further back into earlier US proof coins and sets, I would suggest that you locate a copy of Walter Breen's Encyclopedia of US and Colonial Proof Coins. It is the standard reference work on these coins. You can review its contents online here: http://www.pcgs.com/books/breen-proofs/
