You stat reforging is going to depend on your playstyle and raid comp if you're in a guild/actively raiding. Reforging full haste is going to give you the most throughput, but mastery and even crit builds can be adequate in Dragon Soul. http://us.battle.net/wow/en/forum/topic/3657280029
is a good read and guide to gearing and optimizing.
There are obvious things in your armory you want to fix, namely enchanting your gear. As far as gemming I would only gem hybrid gems when you have a 20+ Intellect socket bonus (or more), and just stick with brilliant inferno rubys/queen's garnets.
As for your holy spec -
1 - Eternal Glory and Last Word are both very strong talents for WoG and would be worth picking up IMO.
2 - Blessed life only works on a few effects in DS. I have used it for a few fights but found it not worth the 2 points.
3 - 2/2 Improved Judgements, even 1/2 isn't need in DS. For the most part you should always be within range to judge without this talent. I use 1/2 basically because I didn't see a better place to toss my extra point.
I would drop 2/2 Blessed life and at least 1/2 Imp Judgements and put those points into Eternal Glory and Last Word.
Glyph wise I would suggest Divine Favor instead of Holy Shock or WoG, Divine Protection is a great glyph for DS, you already have Divine Plea, I use Divinity for the mana return.
