How do I add a title to my cd downloaded music?

I have a few cd's that I saved to the car that I purchased from the store (not downloaded from the Internet) and it just has CD1 then the tracks.
I would like to add the cd title and name of the songs.

How is this done?

I would guess ripping the disc to your computer, changing the tag info, then putting them back on the car in mp3 format would do the trick.
