You have a couple of options.
You could erase the disk and do a TM restore. Yes, that would restore 10.5 and then you'd need to run the 10.6 install again.
Or, you could erase the drive and only install 10.6 and then *the first time it boots up* with 10.6 system, it will boot into Setup Assistant where you can choose to migrate your settings, data, etc. from your TM drive.
I would recommend doing a clean install of OS 10.6 (Which for you might mean installing 10.5, and doing an Erase & Install to 10.6 if you can't install 10.6 directly). While it seems convenient, I have found that installing a new OS on top of an old one is just asking for trouble...any quirks/glitches that have developed can transfer over and even new problems can develop.
If you have a Time Machine backup, you should be able to go back and transfer your Apps/Documents/Files to the fresh install without moving system files (the ones likely to be corrupted/glitchy)
