If I'd want gapless playback with some mp3's I've got over here, then do I have to re-rip the cd's and convert then with lame with some special parameter or something

I haven't tried that version of LAME yet. As I understand it, it's not ready for prime time yet. I'm interested in seeing how it performs.

In the meantime, there are two ways you can get gapless playback:

1) Rip your entire album as one huge song into one single MP3 file. Then use a splitter utility to cut up the MP3 at song boundaries. My GapKiller program includes just such a splitter utility.

2) Hand-trim frames off of the beginning and end of your existing mp3 files to remove the silent bits. This requires some trial-and-error to find the right number of frames to trim. This is what GapKiller does.
