Those are all solid choices for gear that your aiming to pick up. I noticed that your a miner & skinner, which are decent money makers, so if you have the spare gold you might want to consider:
Titanium Earthguard Ring - Item - World of Warcraft
Titanium Earthguard Chain - Item - World of Warcraft
Tempered Titansteel Treads - Item - World of Warcraft
You're going to be running a lot of heroics for your list, and if your pugging, people are going to want to see more HP (its how the uneducated judge a tank), so personally I would be throwing +24 stam gems into pretty much every socket. While gearing up I would ignore any socket bonus unless it is at least +6 stam. Only after hitting around 27k+ unbuffed would I start worrying about your socket bonus.
