prot pally need help gearing
First, let's start with the good. You are geared correctly. Here are a few upgrades to shoot for:
Boots in heroic FoS. Run it every day until you have them. Neck from heroic HoR is nice but not a must have. Iirc, you have lordaerons shield and the one from regular HoR is a minor upgrade as well. Saronite Swordbreaker wrists are a crafted you should have made as well. For trinkets, you want to pair The Black Heart from regular ToC5 and the Glyph of Indom (iLvl 245 triumph vendor).
Next, forget socket bonus. You want the austere earthsiege meta which requires one red and two blue. The blue aren't a concern so gem one agil+stam gem in the best red socket and everything else 30 stam.
You are well over the defense number so enchant cloak with 225 armor and shield with 18 stam.
Chest should be 275 hp enchant.
Helm you want the argent crusade enchant and shoulders you want the pvp enchant (30 stam +15 resil).
Put 22 stam on your boots if you have pursuit of justice and tuskers if you don't have PoJ.
I didn't look at your glove enchant but get either the stam or armor enchant.
There are great threads here about why we stack stam. If you have some moral objection to that, then at least stick with agil, hit, or expertise + stamina hybrid gems when matching sockets. Parry and strength are bad for us prot pallys. Hope this helps.
