Here are some scripts I use to convert mp3s and make audio cds.

Assuming the MP3 files add up to a full 74/80 minute audio cd, make sure 
you have enough disk space to convert the mp3 files to wav, as the wav 
files will be 650 to 700 MB in size. 

First, convert every .mp3 in the current directory to .wav:

#  mp32wav.sh
for f in *.mp3; do
 mpg123 -r 44100 --stereo -w "$f.wav" "$f"

Then, write out the .wav files to a audio CD.

# wav2cd.sh
# replace dev with your cd-rw device
# replace speed with your cd burner speed
cdrecord -v speed=48 --dev=/dev/hdd -eject -pad -sao -audio *.wav

Let us know how it works out.
