I'm assuming here that you're using TRS2006 or one of the TC versions....If you want to transfer content from one computer to another, the best way to do it is to simply copy the "local" folder from within your TRS directory. Then, just paste the contents of that folder into the local folder on the other system. No need to archive.
I'd also suggest copying the assets.tdx and assets.bku files as well. The procedure will work without them, but if you don't have them, everything that you've disabled and re-named in CMP will be reset to it's original state. One of these files is located within the "cache" folder, but since I don't have TRS installed at the moment, I can't check it out.
As for CD types, it's really up to you and what kind of CD drive you have on your system. Anything will work, but if your local folder is quite large, it may be too big for one CD, so you'll have to copy it in two sections.
Good luck.
