A starting point could be the User state migration toolkit (USMT), but this can be a bit laborious.
Take a backup of your whole user profile simply by copying to some other device (external USB key, hard drive, or burn to CD/DVD media)
Specifically for Firefox, all the settings, saved password, favourites etc are stored in the firefox profile folder inside your user profile.
Copy this back in to your new user profile after your re-install before installing Firefox and it will just pick these up. (actually you can copy it in after installing FF, but before is easier. Personally I find this easier than using export/import)
As for emails, what email program are you using?
