Dont hope i get slapped for writing in here but gambon I will give you some advise:)
As I see it you got too much arp pen, and too little haste, If you try look at me or some of the other ret paladins in the guild we have more haste. you need atleast 20% haste + I would say if you sould follow the top players. and around 5.5k AP UB and around 36-39% crit UB aswell.
try check my amory out to see what you can change

adn for the specc and glyphs for my POW it looks fine though you chould change your exo glyph to the vengeance one so you can skip and item with Expertice for haste.
for a ret paladin the main stats are .
1.Haste
2.AP
3.Crit
4.Expertice
5. Arm pen
Thats just my oppinion.
Hope its ok i wrote in here otherwise

slap me
