I haven't encountered a paladin that I could tell was anything but a tweaked 41/20 in my 5v5 team. Divine illumination is pretty tough to give up in intense fights, where it can pretty easily save a bunch of mana when you're chain casting HL on a MS'd target/Multi target healing.

I use a mixture of PvP and PvE gear. Obviously you want a plate piece to replace anything not-plate in your healing set. I like at least having the 2 piece for the resilience set bonus.

I tried putting in some +spell damage, but I really don't have time to make use of it unless we're going to steamroll the other team anyway. The amount of damage I do really doesn't warrent swapping for any spell damage. There's almost always something to cleanse, someone to BoF, or heal, and sometimes it's just best to save the mana.

edit:

Discussing the talents a little bit farther, there isn't much in the way of useful talents outside of a ~41 holy/20 prot build, just pvp/pve differences mostly. There's about 3 talent points you can play around with inside the holy tree with some pretty clear cut lines between pvp/pve talents. Then there's nothing really in ret worth taking, without major sacrifices that aren't justified.
