well...the best sustained dps build for raiding as a warrior is 17/44/0 http://www.wow-europe.com/en/info/basics/talents/warrior/talents.html?tal=35000301302000000000000050 5010550501005312510000000000000000000000


but you might want a bit more in arms, so you could go 26/35/0 so you can get deathwish and a weapon spec www.wow-europe.com/en/info/basics/talents/warrior/talents.html?tal=350203113020105000000000505000550501005310000000000000000000000000

which might not seem like it does as much damage but it can be preferable in pvp if you chose mace spec :)
