The problem is a bit that you need to re-encode the mp3 if you go
through wav or whatever, and lose some quality each time you do that.
There are tools to cut mp3s without re-encoding, but I don't know a name
off the top of my head.

Hart, maybe it would be wiser to rip the stream to w64 (should be fine
with regards to filesize limits), edit it and encode it afterwards. This
way you still have one additional encoding step but it stays at that.
I haven't checked whether lame can handle w64 as input.
