Helm: Never gem parry, especially as a paladin. Gem this with an agi/stam gem, it's much better
Shoulders: Pick up the +30stam/+15resil PvP enchant. You also probably don't need the hit gem here, gem with +30 stam here
Cloak: Enchant with 225 armor
Chest: Change the enchant to 275 HP, +10 stats is REALLY overrated.
Gloves: Change the enchant to either 18 stam or 240 armor (leatherworking kits)
Edit: as far as gearing goes everything looks savvy, the only change I might suggest is getting Pillars of Might since they're actually more EHP than the 277 LoLH, but LoLH are better for Sindragosa/TLK b/c of the large amounts of magic damage.
