From what little I know about Arms Warriors, I can see a few minor issues with your talents. Namely, Truama and Improved Execute aren't maxed. Take a point out of Improved Cleave and Piercing Howl to pay for them.
You'd lose a little utility, but gain a small amount of extra DPS.
As for gear and rotation, I'm not well clued up on the subject. I'll leave that to someone else.
you should gem for ArP once you around 30% from gear alone.
As for rotation there arent really anyone, since our abilities rely on procs, however there is a priority list, which is: MS>exe>overpower>slam. Only use blade storm if the first three arent up or you need rage.
