in terms of mana you're kinda sol. what i mean is that the primary way a pally receives mana to pew pew pew is through blessing of sanctuary, seal of wisdom and to judge wisdom. most efficiently, the one getting attacked will be the one with NO mana problems. the one that's not being attacked will regain mana from seal+judge. no blessing. and blessing gives you the most mana back too.

as far as dps. you're gonna have to tell us your specs. prot plays a lot differently from ret. even though it might seem all the same, seal, hammer, judge... there are different priorities, plus we do get different abilities in the different trees.

to help you with loot, give the slave a macro to change view to face down, kinda, and zoomed in. then have a button that will simulate a mouseclick and your'e set. dont know i think i've given uou enough keywords to do a sufficient search. hehe. good luck!
