Bookmarks and settings are held in your profile.

Profiles - Where Firefox stores your bookmarks, passwords and other user data

Beta software is for testing. There is always the possibility that it will screw up your profile and you will have to delete it.

You should preferably create a separate profile for the beta version. Alternatively backup (copy) your profile so that you can restore it.

If you're sure that Firefox 4 betas are always going to work then you can delete other versions. But I wouldn't.
