Time Machine reports it cannot back up an internal 160 Gig drive to an external 160 SSD drive because it has 240 + to back up and it won't fit.

Go to the Time Machine preferences, and then hit the options button to see what is being backed up (hint: everything not in that list). So if this is a Mac Pro or a later model iMac with two internal drives, it will default to trying to back those up too, not just the boot drive.
