Here is a link to the spec I would recommend
Talent Calculator - World of Warcraft
For the spec I linked there are 2 points in Weapon Mastery. Each point in Weapon Mastery is equal to 1% expertise which is 4 points. I did this so you can get rid of some of those expertise gems
I put two points in Improved Slam because you should be using Slam when nothing is proc'ing slams should be in the 5 - 10% range of your total DPS.
The 5 points in unbridled wrath are pointless you shouldn't ever be rage starved as an Arms Warrior.
Also your gemming is a mess
Meta should be relentless Earthsiege Diamond
Use a nightmare Tear to activate it (stick this in whatever socket you want the bonus from
Once you get to 30% ArP from gear alone (not counting the 10% from battlestance) start gemming for ArP.
Till you get there use all Str Gems toss away those yellow and purple gems and you should be able to get rid of both those expertise gems as well.
And get enchants for your shoulders, cloak, chest, wrist, helmet, and boots
