i want to reset my phone to factory...i am having problems with my patches and themes not showing up and i can't delete any.

i have 3 questions-

if i do the back up as directed here:


1- will my sms/call logs, contacts, calendar, settings, music and photoes be restored?? i don't want to lose that stuff. Basically what is inculded in the database.db3 file??

2- will this file restore the themes and patches i am trying to get rid of??

3- being that i can not access my theme/patches to remove, what kind of factory reset would be best?? just the reset on the phone or use WebOS doctor??

I've tried to search and find this info, have even asked but can't seem to get a straight answer- just frustrated at this point. any help would be greatly appreciated. thanks!
