I would change your spec around to something a bit more traditional. Improved Charge isn't doing a lot for you, and you don't have imp sunder (lowers the rage cost of devastate).
Do something like:
8/5/44 (+4 to spend as you want in the prot tree) -- (Survivability) Talent Calculator - World of Warcraft
12/5/44 -- (Threat) Talent Calculator - World of Warcraft
As far as gear goes:
Put +12 sta on your wrists
Your gemming is a little confusing since you are not getting socket bonuses. You have enough defense to put +12 sta gems in place of your hybrid gems if you aren't specifically going after a socket bonus.
You have pretty decent gear for not venturing much beyond heroic 5mans. As you collect badges I would think you would probably want to buy [item]Slikk's Cloak of Placation[/item] x35 badges, possibly the new ring [item]Ring of the Stalwart Protector[/item] x60 badges, then start saving to replace your legs or bp (with the 2.4 versions). Your priority may change if you start entering Kara and beyond.
The beast is getting hungrier.
