I don't actually think there are any extra apps in the v3b image. But if you want to make Maemo icons for Debian apps, you can just copy the ooo.desktop file in /usr/share/applications/hildon to a new name, then change the Name, GenericName, Exec, and Icon fields. The new Exec field should be:
Exec=debbie <command>

The one thing that might not work is the sound...
