First of all, get PallyPower. It's an addon that tells other pallys what types of improved talents that you have taken, be it imp might, imp wisdom, imp devo aura, Blessing of Sanctuary. 

Second, if you don't have some other raid frames besides just using the default UI's raid frames, you are seriously gimping yourself. There's a reason top guilds who fraps their videos ALWAYS have some raid frames be it grid or something else. It allows you to know the state of the raid, be it someone sitting in fire, have a curse/magic/poison debuff, etc.

Third, time and time again, we get prot pally apps who say the same thing OVER and OVER and OVER : "I have never had a threat issue". They get plopped into one of our raids, and an overzealous mage or warlock either pulls aggro, or gets 1 shotted. Why? Is it the fault of the dps who died or pulled aggro? No!! The tank never took talents that would have simply maxed their threat. You are missing a 7 crucial talents even to max your threat : 1/2 imp judgement, 3/5 conviction, and 3/3 Crusade. Leave BoM to the ret pallys or warriors to battle shout. Put tuskers vitality instead of 22 stam to your boots, and you can free up another 2 points from PoJ(they don't stack together and bosses don't disarm you). You say you're a theorycrafter: why didn't you think about this? All the prot pally theorycrafting is all based at maintankadin.failsafedesign.com . Do you go here? And why did you get the Glyph of shield or rightness? It's already cheap enough to spend mana, yet you want to spend 80% less on it? Leave this glyph to the pvp holy paladins. Take the Glyph of SoV for free expertise

Fourth, your professions......You have 450/450 mining, but why do you have 125/255 Blacksmithing? You're missing out on 2 sockets that you could have gemmed with stam or str/stam in preparation for 3.2.2.
