The Archive and Install feature saves your settings, preferences and data, as well as third party apps that are in the Applications folder. However, it does not archive the OS itself. To be able to go back to the old OS, you will have had to backup/clone your entire HDD to an external Firewire HDD, then you would be able to clone it back.
If you are unable to get the wrinkles in your current installation ironed out you may need to backup, at least, your Users Folder, and then do a complete re-install. Before you do that, however, if you don't mind repeating it, what are the specific problems that are troubling, and what measures have you taken to remedy them up until now?
Good luck.
