Assuming you want to keep divinity, I would suggest this build:
The World of Warcraft Armory
Conviction will give you better return than SotP. Most folks go without divinity and put those points in divine guardian and crusade, but divinity is a valid choice.
You can dump the glyph of spiritual attunement and go with glyph of vengence. I would also suggest glyph of divine plea (3% damage reduction) instead of either Glyph of HotR or judgement (if you're fine on boss fights, I'd dump judgement and keep the 4 add ability). Add Lay on Hands and Sense Undead as your minor glyphs. Probably dump might.
Your gear looks fine for where you are in progression. Keep grinding wrymrest rep until you get breastplate of the solemn council. If you haven't already done so, pick up essence of gossamer from h AN. Hope for dragonbrood legguards from your H OS runs. The two slots that I used for my 2 piece set bonus were shoulders and hands as both are near best in slot (for the level). The T7 chest is also an upgrade over breastplate of the solmen council, but if you can get one of the naxx chests to drop, you're better off. If not, by then you'll have enough badges to buy the T7 piece, i'd just buy it last unless you're having problems getting into naxx runs.
I prefer the Stam/armor meta gem, but you may have to swap that a couple of times as your gear moves around.
