Did you use Titanium, Astro or Mybackup to back them up? If not, they aren't on your sdcard.
The best way to get ALL your settings and stuff back to how you had them on UD 7.0 (including bookmarks, texts, website signin info, apps, home setup) is to do the following:
Restore your advanced nandroid backup of UD 7.0
Make a new advanced nandroid backup of DATA ONLY (uncheck all boxes except DATA)
back out to the main menu.
Wipe data/clear cache 3 times.
Install 8.0
Restore your backup of Data only.
P.S. This is what i do EVERY upgrade for UD. It restores ALL of my settings, bookmarks, texts, apps, etc. So far it has never failed. I got rid of Titanium and Mybackup long ago.
Good luck
