You should have archived the iDVD projects before burning the DVDs. The encoded files become part of the iDVD project files, bloating them up. There might be a way to go into the file and delete only the media without touching the design elements, but I'm not familiar with the method.
The FCP full-quality QuickTime movie files would be too large to archive. If you want to save a copy, output to tape or buy an external drive. For backup purposes, a USB drive would do fine, though FireWire is far more versatile.
As for editing materials, no, JPEGs and AIFF audio files are not timecoded. You have to backup all of them in their original form in order to re-create the editing project. Use data DVDs or, again, an external drive.
