Well, there's hit and run from Drow of the Underdark - give up heavy armor for + 2 to initiative and dex to damage to flat-footed opponents within 30 feet. There are three in PHB II - overwhelming attack, coutnerattack, and I think some sort of parry. There are racial fighter substitution levels for warforged, half-elves, dwarves, and raptorans ( I think) from the (Races of) books. There is also dungeoncrasher from Dungeponscape that let's you get extra damage when bullrushing opponents against walls and makes it easier to break down doors. There may be some in Complete Mage and Complete Champion, but I don't have those books. That's all I can think of right now.
