Signable Cubs pitchers?

With Ryan Dempster and Kerry Wood needing new deals for 2009, here's wondering how quickly the Cubs can act. With the team's sale taking a long time to get done, and with both players finishing off outstanding 2008 seasons, how deep into the pocket book can the Cubs go? Can they afford to wait until the sale until they lock up these two with good deals?

I'd assume Dempster and Wood would be very willing to sign with Chicago, considering the patience the Cubs have had with their previous injury histories. Both seem to enjoy playing on Chicago's North side for manager Lou Piniella, who already was extended through 2010.
