If you have the original files lossless, then Audacity can edit FLAC aswell. After editing you can save edited file in flac, then convert to mp3 with fb2k or something similar. Thats the best way imo
No need for foobar2000 in this case; Audacity will also export as MP3 provided you have the LAME executable available.
