Just a note - you are using the /classic/ template, which means that if you ever upgrade to a newer version (they come out every couple of months or so), you will completely lose all your customizations.
The easiest course for you at present will probably be to find all /classic/ folders on your site and copy them while changing the folder name to/custom/ or whatever you like. The new folders should sit right next to the /classic/ folders.
Then find your template_info.php file and change information to reflect the new setup, and turn your template on in admin > Tools.
See the FAQ for more detailed information.
