Judging from the fact that hits are being parried, this says to me you are attacking from the front of the mobs. If you move to the back of anything you are attacking, you push parry off of the attack table, which will automatically boost your DPS. [link is a little out of date, but gives the general idea]
However, this is the key point to take away from this answer: Move behind the target for a dps boost.
As for your miss rate - don't worry about them too much for white damage [ie, auto attack], as that requires a stupid amount of hit to remove - 27%, or 886 +hit], but it is at special attacks you need to care about.
Since you have 3/3 Precision, you need 5% - or 164 +hit to take misses off your special attacks, therefore you can safely change out gear with hit on it for other stats.
Your expertise is at 24, and as a human, if you can ever replace your mainhand with an Axe, with no other change in stats, it would boost to 26. This would push dodges off of the attack table. [this is why you're only seeing 3% dodge - you're almost there]
[edit: comparing against EJ's Warrior FAQ, stat priority is 8% hit inc precision [ie, 5%], 26 expertise, then Str > ArP > crit > agi]
Your meta-gem isn't active, which is costing you some crit. I'm not too up on Fury warriors to know what to put in, but you'll want to swap out a couple of gems.
Finally - enchants! You're missing a load of them. There's no excuse for having no enchants on your gear, even if you just have a lower version while you get the gold for the accepted one.
For instance, on your chest, you want Powerful Stats, but if you can't afford that, you can easily make do with Super Stats at a fraction of the price and only a 2% drop in effect. That single enchant would give you a boost of ~8% to your strength and agility, which means more delicious DPS.
There is no instance where having an acceptable enchant will cost you DPS.
On BOTH weapons, you want to aim for Berserking - Use Massacre until you can afford them [as you have on the offhand]
Edit:
There's much that can't be determined without someone experienced reading a combat log parse to see what you may or may not be doing wrong.
Further information could be needed. For instance:
- Are you ever rage starved?
- Do you use any macros?
- Key binds, or using the mouse to click the action buttons?
- Average latency of your internet connection to WoW?
- Are you using consumables?
- Are you using any addons to assist in reminding you to do certain things? [ie, when bloodsurge procs]
This answer can only offer small tips to boost your DPS a little. Definitely practice against the combat dummies in the cities.
Check out the spreadsheet linked from EJ, and start experimenting with enchants and gemming against yout current gear to see how you can improve DPS without changing anything you're doing otherwise.
Finally final [in this edit]: If you're applying Sunders when no-one else is supplying a similar debuff, you can reduce the concern a little on your DPS, as you're increasing the overall DPS of the rest of the raid/party
