In the raid group I run with, typically we have all the warriors spread out with the elites they're tanking to keep cleave damage down to a minimum, so for managing Domo's agro, we have all the hunters sic their pets on Domo with taunt on. Does a fairly decent job of keeping him in one place.\
Edit:
And as to kill order... since they become sheep immune once 4 are killed and we don't like having any healers around to do anything... 1 elite, then all 4 healers, then the last 3 elites. Just make sure whoever's watching the tanks on the elites are not wasting mana, and you can hold out for a long long long time (usually we assign a priest/druid/paladin team, and unless we have healer deaths elsewhere, we end up at maybe 1/4 - 1/2 mana if we're on the last elite to go down).
