Well if you have the NWN games just reading the manual is easiest, but I get lazy some times too and just ask people. There's only one special fighter feat that is unique to fighters that you need to worry about. Weapon Specialization. That gives +2 to attack rolls with a certain weapon of your choice. There is an Epic feat later that gives +4 but since no fighter's gotten there yet you probably don't need to worry about it.
Also fighters do get feats every third level so levels 1, 3, 6, 9, 12, 15, and 18, but they also get a bonus feat every even numbered level 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Also I'd like to add the advice I give everyone, try not to plan out how y ou want your character to level until he/she's level 20. The first five or ten levels are cool, but you never know when RP may change the development of your character.
