Point is, they won't ever sound better. MP3 makes the sound different,
and Vorbis will encode those differences and add its own. If you're
lucky, you'll notice no significant degration from the MP3, but it will
not be anywhere near "great", "good" or so. Note that Xing sounds even
bad at 320kbps, and no matter what -q you encode those tunes with,
they'll always be just Xing quality. (I can actually notice this on some
tunes that are otherwise transparent to me at lame --alt-preset standard
(~200 kbps) or Vorbis @ -q 5 (~160 kbps))

Going through the pain of re-ripping the CDs to Vorbis is definitely the
recommended way (or encoding your lossless copies), as well as leaving
those MP3s the way they are.
