Yeah, you get that quest now automatically when you hit 50, so if you were already 50 it will appear, (I seem to remember it coming through the mail). Anyway, unless you are already in Columni or better, get the Tionese Force Mystic set, since you are a healer.
I skip the Tionese and start doing HM's to build up Black Hole comms in order to go straight to BH gear. Then I rip the mods out of that and put it in what I want to wear.
