Hey, I recently just did this with some of my static (two days ago) so I can give advice. Having a Ninja/SMN or BLM combo is ideal for both trash pulls and boss fights. Paladin is the best tank due to having both silence and stun, more notably having stun on GCD for floors with no abilities. Stock up your pomanders for floor 190+ as the debuffs for floors are much more frequent and stack in terrible ways (we had two no items no abilities, and two no abilities with gloom). Finally, try to get as close to capping your aether as possible, as higher level bosses will take a lot to finish. Good luck!
