So I have played a few games, I have really begun to have fun with PFS. The more I learn about Pathfinder, the more I am encouraged to keep playing and learning more. I am enjoying this RPG. However, each time I learn something I am finding that my previous choices/decisions/purchases may not have been the most correct, or in some cases were illegal in PFS.

For instance: I purchased a Masterwork Quarterstaff after my first game -> what I now know is an illegal purchase. The Quarterstaff is a double weapon. "The masterwork quality adds 300 gp to the cost of a normal weapon. Adding the masterwork quality to a double weapon costs twice the normal increase (+600 gp)." - Ultimate Equiptment, Paizo 2012.

This After my first game I earned 2PP/Fame; to spend over 500gp, I needed 9PP/Fame.

This cost me 600gp, this was well out of my purchase range for a Fame of 2. I believe this purchase was illegal, Should I remove this and other illegal purchases I made in the past or continue using it since I now have 10PP/Fame?

I was wondering if the Blue Book is legal?

BLUE BOOK
Price 5 gp; Weight 1 lb.
This book details the seedier entertainment establishments in one major city. It contains the names of brothels, burlesque houses, and gambling halls in that city. By consulting the book for 1 hour, for the next 24 hours you gain a +2 circumstance bonus on Knowledge (local), Bluff, and Diplomacy checks to gather or use information in that city. At the GM's discretion, you can use it in settlements near that city for a +1 bonus.
