All Pathfinder products are available for play, subject to GM approval. Pathfinder products produced by Paizo are approved without question, though some older material (written before the final PFRPG rules) may need minor adjustment. Most Pathfinder (PFRPG) products by 3rd party producers under the OGL are available, but you need to verify the source material with me to make sure that I have it.
You may select any class from a Pathfinder source book (Paizo or 3rd party). Races are restricted to Pathfinder Core and Advanced Race Guide only. (GM has the right to reject any combination that does not fit the setting.)
No D&D 3.0 or 3.5 books are allowed for player use.
