It's ok that you don't have CDs for the other things, you can download most (or all) of the drivers you'll need from the manufacturers' websites. I advise you do that before you format.
If you can tell us your full system specs (models and manufacturers of parts) I'm sure we can help you find everything you need.
Also, you'll want to backup any important files, music, etc. that you can't replace. Best to back them up onto a CD since you'll be formatting, unless you'd rather place them on another partition of the hard drive.
