Here's what I can tell you from my personal experience with bears:
Agility and Stamina are king. I don't think anyone will ever dispute that really.
We need 961 (rounded up) hit rating to be 8% hit capped.
We need 781 (rounded up) expertise to be dodge-capped.
Parry cap is 1682 expertise, so I wouldn't even worry about that.
Hit and Expertise are our biggest threat stats. Do we necessarily have to be capped? Not... necessarily, but we're probably gimping our threat generation the farther from it we are.
Our Mastery is FUCKING AMAZING, even after the nerf. We should probably devour it up. I have no theory to back it up, but I would even suggest reforging all haste into mastery once we're close to the hit/expertise levels we need.
Our Mastery ALSO only procs off of crits so crit rating is going to matter to a point as well.
This list is all heroic dungeon level items or higher (such as crafted/reputation items). You will see a little overlap from my previous list, but only because of item level. I'm also ignoring any resilience gear, as it's generally not as good for raiding as it's item level belies.
This list is set up very similarly to the last one, with a couple additions. After I name an item, i'll list where it's procured from, and it's "green stats". Mastery, haste, crit, hit, expertise are all green stats. All of these items generally have 2 of them in some combination, so it is up to you to decide which ones would be more beneficial to your bear, based on the gear you already have. And so, with that out of the way, on to the list!

You'll notice I didn't include Trinkets in this list... there's a wee bit of laziness in that, on my end, so I apologize for that. The main problem with trinkets is that some of them provide substantial bonuses (agility stacks, large on-use mastery bonuses, etc) that without knowing a bit more about proc rates, uptimes, and stat-weights I can't make very well informed decisions about trinkets. Sorry about that folks! Hope the rest of this list is very useful to you, and again if you have questions/comments/disputes about anything I listed, feel free to comment!
