I like Inge for a bench position (as he's likely eligible at more than one position, C being one). I'd drop Burnitz to pick Inge up.
Honestly, I kind of like your rotation and while I'd probably put the back end of it (Perez, Wells, Pineiro, Lopez) on the trading block, I wouldn't make any rash moves just yet. See what they're worth to the rest of the league.
I think you should try to move Hafner, Broussard, Jones, V Wells or Edmonds to try to get a closer and/or a SS. The better the player you give up, the better CP/SS you'll get.
This is what I'd do at this point:
Look around the other teams and see if anything fits (i.e. they two good players eligible at SS and three closers or more) and see if they could use one of your 1B or OF guys.
If that doesn't seem to work, post your trading block to the league board, the offers will fly in. Most of them will be laughable, but you can counter back and forth until you've got something that will work.
