I'd send Ian Kennedy down to SWB and let him know he is staying there for the remainder of the '08 season.
The only other starters I would consider bringing up going forward should the team need a body would be Karstens or Steven White. And publicly declare so Kei Igawa's name would never have to be mentioned again as a possibility.
I would move Joba to the starting rotation.
I would bring up Old Prof's man crush J.B. Cox to be the 8th inning guy.
I would bring up Brett Gardner and Juan Miranda.
I would send down Duncan, and try to package Melkey and Ensberg in a trade to obtain a catching prospect.
I would bench Cano and play Gonzalez.
I would bring in Paul O'Neil as my bench coach and Tino Martinez as 1b Coach.
Finally, I would let these guys know that if they didn't start showing some heart out there that they had better start looking for apartments in places like Pittsburgh, Cincinati, Texas, and Seattle.
