If you back up the BB, and then after a period of time, for whatever reason, you reinstall the backup file, will the theme and all settings revert to date of last backup?

yes, only if you are using a theme that comes with the phone. If you have purchased a third party theme, you will have to back that up seperately.

rite on the head. youll also retain all call logs emails and text. kinda annoying.
