You've got a few players in the minors who'll help, Guitterez in AAA could play a passable SS, for instance. Not much pitching help.
There are no "hard" rules on what constitute BL-quality but I use 70 splits(for both pitching and hitting) as BL average. Start looking there. And, considering your current state, consider platoons because you don't have many 70/70 split hitters.
