OMG, Darlene, I don't think anybody uses CDs anymore.
External storage drives are cheap. Get one or two. Copy all the important data on your computer to the external drives. You should have or can get backup software that does periodic backups automatically on a schedule.
Some people keep a copy of the data on their computer on a local external drive, another drive kept off site (friend's or relative's house), and another copy in the cloud (web-based storage).
If you were a Mac user, I'd suggest using Aperture for organizing and editing. I think you have Picasa. Doesn't that have an organization component?
