I use smartres, I just smash a button and my guys rez the nearest unreleased rezer and after all the rezers are rezed it rezes the rest. If also knows if someone is already rezing a person so it will pick a person that isn't being rezed. Its one of the only addons I butched, it has some lame ass logic for dealing with people that have released and what not and overly complicated keybinding and frame nonsense.

As far as your macro goes, perhaps /targetparty will work for this.
