I ran a new game yesterday for some friends; 2 have never role-played before, one hasn't played in 20 years, and the other started 3 months ago.
So during character creation we used PHB 3.5, FR Campaign Setting, FR Races of Faerun, FR Players Guide to Faerun, and FR Faith & Pantheons. Once we started with the adventure we added DMG & MM 3.5, the Sunless Citadel, and I looked up the Vow of Poverty in the Book of Exalted Deeds.
