Directory of MP3 -> redbook cd

I tried googling, but i am not sure what im looking for or how to ask it. I have 17 directories of mp3s I want to burn as redbook audio to cds. each directory is 1 cd. in each directory the files are numbered 01.mp 02.mp3 and etc. those numbers correspond to the track order I want (alphabetical/numeric).

How do i go about doing this.

Also, I dont necessarily want to direct burn, maybe I only want to make 17 cd images so I can burn multiple copies.

Most CD burning progs should be able to do most of this for you. I know Nero 6 does. Add your MP3 tracks to make a CD, then burn to an image file instead of a disc. The software takes care of converting to the proper Red Book standard. Then just repeat 16 times.
