Get the your HQ jewelry - maybe mix tourmaline and turquoise depending on how your mana usage is. I wouldn't bother with i55 crafted stuff for the moment, just to be cheap.

Run AKs or WPs in your AF. If you're not in a bad party you'll be fine. (Though a WP "speed run" might be beyond your output for the moment)
Replace AF with strategos. Buy DL stuff to replace non-strategos stuff first (usually belt is the #1, I think). Then replace strategos stuff.

Once you've got most of your gear try to get through the ifrit/garuda maybe farm garuda for the weapon. Get relic stuff done, titan when you're >3200hp.
