Pretty much all of the Pathfinder rules were released under the OGL license (which they had to, since they created those rules based on the OGL rules released by Wizards of the Coast). Unless I am very much mistaken, the site I linked to is perfectly legal.

Paizo has an official Pathfinder Reference Document. Of the two I generally prefer to use the PRD. However for the d20 rules the d20 SRD is the gold standard.
