How should I go about upgrading gear?

 The gear (huge image warning)

Yes, I know. Most of it is badly scrolled. I'm waiting for Innocence scrolls to come back to the Cash Shop (or for a period of time where I can just throw cash at cubes and buy new Empress gear). In the meantime, though, what can/should I do to improve my damage?

My meso budget is 4b and my NX budget is currently nonexistent (for the next couple weeks.. we'll see about after).

Thanks in advance.
