I dunno, looks to me like you've got everything handled. You're just in farming run mode to pick up more loot. If you wanted more stam you could probably switch out the gem in your belt and the enchant on your chest, but that's pretty nitpicky.
I especially like your spec since it's point for point the same one I'm using
Enchant boots, get your belt buckle, drop a tad of defense for some bit of avoidance though that'll keep coming from gear upgrades as you replace all your rare quality stuff with epics. Spec looks like a good choice, probably what I'll go for on my warrior when I finish leveling my old tank character. I'd also suggest raising your hit and expertise where you can. Basically make yourself a list of what you want for items to improve your survivability and threat out of the raids that drop gear you're doing. from that itemize it with the best gems and enchants you can get and try to enchant/gem as you pick up those pieces in the random environment that happens as things drop in raids. And when the opurtunity arises to possibly do Pickup groups to the 25man in wintergrasp hit that up since it offers you the chance to possibly get one or more peices of the 25man version of your dreadnaught. Though if you're only doing 10mans on a regular basis the drops from heroics and the 10mans itself are all you really need to progress through it
