Hey, Halon, I moved all of my old Droid sd card folders onto my Nexus because that was where I kept all my data and books, pictures, ringtones, etc., and let the apps reinstall from android market. They did that automatically. It was fast! Then I got my phone pretty much how I wanted it making sure the apps restored the data. Some of them needed Titanium Backup and some could just use the backups from the card. Finally, I did the part with ROM Manager. Worked out well as now my backup will have everything perfect. I don't know if that helps at all?
Unfortunately I wiped my Thunderbolt and sdcard before I thought of that
