I'm in the same sort of situation but a little different. To be honest I wouldn't touch Peavy or Harden.... And probably not Lewis either. I think now that Marcum is healthy he can be pretty steady and Garcia is just killing it and has a ton of upside. The problem is who to drop on your team..... Past Rauch your RP don't look all that great unless Lidge can return to form... but thats a BIG if. so if you want to pick up on of them my options would be either Marcum or Garcia and drop either Lidge or Perez.
