Tank-N-Nraining Needs Input

First things first heres my armory link The World of Warcraft Armory


Now that’s out of the way I have to tell you that I have only been playing WOW for 3 or 4 months and so i think its safe to say that i am inexperienced to say the least but anyway I decided to roll a prot warrior and I Just started to run Naxx 10 man last night . I would like need any advice you all could give me on what stats, gear, gems, talents that would be best to be a good main tank.. i know i have gear that’s under par and other things that are a little off but I’m kinda at a stand still and don’t really know what else to do .. I mean I don’t want to start making what i would consider upgrades just to find out I was wrong . lol. any advice would be greatly appreciated Thanx

Your talent setup is fine, I would remove 3 points from Shield Spec, and put them into Deep Wounds. As for gear, your great for Def/Exper however you drastically need more hit. Your going to want to look for about 180-190 more hit. I have provided a list of items you can try and grab out of heroics/crafting that will give you some sizeable upgrades that will help alot in your naxx10 progression.
