i strongly recommend to make a clean deinstallation of all the addons you don't need anymore.
(have you thought about the junk that remains in your db even without the files?)
but if you really want to go that way, just upload the fresh vb files, import your database dump, and reupp everything that's missing like attachments, avatars, style graphics and so on, you will see what is needed
but better don't do it like that
