You have points in arms, but not deep wounds.
I highly recommend taking deep wounds if you are gonna spec that deep into arms. Something akin to
15/5/51.
You can take the two points out of cruelty and play with them a bit. Armored to the Teeth is better points than cruelty.
I'm looking at your socket choices. You don't need to, for min/max, socket match for bonuses. The 30 stam gem is all I suggest you need, except for meta gem requirements. Hopefully you can get your 535 defense skill for heroics with out gems. 540 is for raids, which you'll want a little different gear for anyhow.
Their is no reason you shouldn't be doing as many non-stop heroics as possible. Get a good set of T9, and a few miscellaneous other stuff.
The Badge of Triumph gear is all what you want to gear for. Badge of Frost gear will take a while, but it's worth it to get the badge of triumph gear first. Just don't convert too many BoF to BoT in sacrifice.
