I can't look at your gear since you're in Fury spec, but you shouldn't be worrying about hit/expertise. Your technique will get you a lot farther than your hit stats.
Sounds like your ability priorities are reasonable, so the next thing I'll ask is are you marking kill targets? Putting a skull on the main target makes it much easier to hold aggro, since people will be attacking that target, and you only need enough threat to hold off the healer on the other targets. I'll often start a pull with a Thunderclap, Shockwave, Shield Slam, Rend, Thunderclap, or something similar, then go to town on the skull target with cleaves thrown in almost on cooldown. If we're AoEing the targets, I'll tab around and toss devastates on the other targets as well.
