I would pick up Huff in a heartbeat and seriously consider Moss. Olerud is good, but you really don't need him. Gottabelieve is right about your OF; nothing spectacular, a lot of fairly decent guys but nobody who commands respect.
Some real queston marks in your rotation. Burnett's arm WILL fall off; just a matter of when, not if. Wolf, Perez, Washburn: will they do it again? I would parlay your IF and RP depth into a big OF guy and or another solid starter for your rotation.
Otherwise, you look good......pick up Huff NOW!!!
