I encourage everyone to register a paizo account, get a PFS number, and read the free pdf, Guide to Pathfinder Society Organized Play on this page.
Also, there is a great free online player reference guide. It is a lot of information to take in at once, I recommend you stick with content in the core rulebook.
There are character sheets in the guide to organized play above, or you can use the excellent and free PC Gen, it even has a Pathfinder Society setting. There is a lot of superfluous information there are well which may make it difficult to use starting out.
