What books should I buy to play with an average D&D group?

I have already bought all three 4th edition Player's Handbooks, Dungeon Master's Guide, Monster Manual, dice, Dungeon Tiles, Plan escape tile map set, and several tubes of dice, but have recently learned that 4th edition isn't too popular with some subgroups of gamers. While the nearest game store is a state away (and thus will likely play online), I prefer having books to read in my spare time and want to one day join a physical group. My question is, what books I buy so that I could easily join an average group of Dungeons and Dragons players of with few problems and without me inconveniencing people too much?
