As a public service, I thought I’d reiterate the two links you need if you are playing Pathfinder (besides paizo.com and this blog of course!). Apparently not everyone knows about them, and one has moved!
The Pathfinder SRD, which has all the OGL rules from Paizo (pretty much all of it) and a variety of third parties. If you need to look up a rule, here you go! It’s always kept super up to date, even new beta playtest stuff shows up here ASAP, as well as sometimes links to useful rulings from the Paizo boards, etc.
The Pathfinder Wiki, which has a primer on the entire setting of Golarion. Beware – it moved without warning and the old site is still up! If you are using a wikia.com address, stop, switch to pathfinderwiki.com. Up until today even I have been misrouting people in my blogroll. I have tried to figure out how to contribute a couple times and have run away, tail between my legs – I couldn’t even figure out how to leave a forum post saying “set up a redirect or something guys” in their system. But it’s a great place to search for that mostly-forgotten reference or link your players to in order to get them briefed on a country or something.
Oh, heck, here’s a third link. No, not the Pathfinder Database, for fan created content, which I wish well and all but there’s just not a lot of quality content there so I don’t use it. But this is my #3 go to for Pathfinder…
Hero Lab, the best character builder tool for Pathfinder, many hands down. I don’t build NPCs above 3rd level without it. I’ve tried PCGen and RPGXplorer but IMO those weren’t any more helpful than doing it myself. Now, it’s for pay, and they’ll charge you for each additional bit of rules they add from the various Paizo stuff, but they’re “official” so they do have it all. I wish all the NPCs from the APs were downloadable from somewhere, that would be a huge time saver. One of our players even uses it at the table to roll and apply conditions to his PC.
