Unless my info is out of date, you are slightly over the hit cap (8%). Haven't read up on the EJ Ret Paladin thread in a couple weeks but that was my understanding.
Overall you have some very nice gear. Couple areas you could make some improvement are to:
- Enchant your helm, Arcanum of Torment
- Either Major Agility (22 Agi) or Greater Speed (23 haste) for your cape
- Replace expertise on bracers with Greater Assault (35 AP)
- Replace +20 hit on gloves with Crusher (44 AP)
- Replace 16 agi on boots with Greater Assault (32 AP)
- Replace expertise gem in ring with Bold Scarlet Ruby
