Paladin AOE farming gear help

Hello guys I've made my paladin to AOE farm and collect cloth, green items from 67/68 level tbc dungeons and 77-80 level icecrown pack of mobs.
Can you give me suggestion how to gear him for this scenario limited to PoS,FoS,Hor and EoT. I'm running 0/53/18 spec and I think about going full tank gear (2xt9 for hammer dmg) with STR gems for more offensive power, 2.6k agility weapon and shield with spikes enchant. Should i look for specific stats, Do i need def cap... I need to have good sustain but still dmg to clear fast.. What would u recommend guys.

I would recommend you gear a ret paladin and get to level 80 as fast as possible and farm with epic dps gear, kill everything so easy, so fast. make like 5k a day just chillin'
