Ill help you out a bit. You already have a nightmares tear in your gear so change your meta gem to the 21 agility 3% crit gem, replace those 2 stam str gems with pure str. Your spec is ok, i would drop the 3 in healing light and throw 2 of them into PoJ, take 5 out of divinity and then get divine sacrifice so your spec would be 5/11/55. Your glyphs you should change glyph of holy wrath into Seal of Vengeance since you're only at 14 expertise and you need 26, and change glyph of avenging wrath into glyph of consecration,glyph of avenging wrath is so situational its a joke and usually ends up being a mana hog, consecration glyph would help loosen up your rotation a tiny bit and it gives you some mana efficiency dropping consecrates every 10 instead of every 8. As for your holy spec i would recommend dropping purifying power and pure of heart as those are more pvp oriented talents and getting 5/5 into judgements of the pure. I would also look into getting aura mastery, it is a pretty powerful talent when used right.
also drop the holy shock and seal of light glyph in your holy set and pick up either the LoH one or beacon and seal of wisdom for the reduced mana cost.
