I did something very similar to convert a batch of wave files to mp3 using 
lame.  Use basename to get the file name without the extention and then 
rename the files on the command line.

ls *.wav |
   while read file
   do
      FILENAME=`basename "$file" .wav`
      lame -q ${QUALITY} -b ${BITRATE} -s ${SFREQ} \
	 --bitwidth ${BITWIDTH} -m ${MODE} \
	 "${FILENAME}.wav" "./mp3/${FILENAME}.mp3"
   done
