Im no longer a DPS warrior, im a tank, but i would advise the following equipment:
1] rejuv amulet, or at least a regen one to keep your mana up, so you can skill hit all the time. This also allows you to put your focus stat points in strength - extra damage.
2] haste gloves too, to speed up your attacks either gold or heroic
3] dont have a shield, either use a two handed weapon or a offhand, along with your main weapon
4] in terms of weapons, this is realy where opinions will vary; i used the gold king frostbelly two handed sword, as it hit really hard (and with haste gloves not that slow either), however you cant purchase that and the guy that drops it has gone, so as an alternative i used the ancient falchion and golden blade of battle - but there are other offhands to get - just make sure your abilties are maxed on what ever weapon type you use eg sword ability, axe abilty etc
Another important thing to consider is your stat points setup - which is probably covered in another post.
Hope that helps, although others may want to post to aid you - good luck and happy killing...
