I am a little confused as to how to backup the download. Can I simply move/download the two unzipped files to a CD? I know this sounds like a silly question, but I have never actually done it before. I'm used to a JPEG here, a BMP there...

Burning a copy of them to a disc is one way to do it. You'll need to use a DVD disc (should fit on one disc) tho since the files are too big to fit on CD discs (Program file s/b 'bout 1.6gb & the Content file 'bout 900mb). You'll also want to make sure you have the Serial # you received by email backed up. You could type thtat info into a text file ( <filename>.txt ) and burn that to the disc along with the install files. You can also use a marker and write it on the disc. You should be able to use either the Creator Classic app or the Data Disc portion of the home app to burn the disc. I would burn two discs myself just in case one gets damaged or lost.
You could also copy them to a second hard drive if you have one. The idea is to have at least one (two is better) backup copy of the files in case anything happens to the ones on your main system, such as a hard drive failure or a system crash.
