I'm not much further along than you are but I'll try to give you some info. (Someone correct me if I'm wrong)
I understand that when a WAV file is moved from one directory to another none of the trac info goes with it. So I don't understand why you are getting even partial trac info, unless you are using WavPac and not just WAV.
In any case, as I understand it, WAV can be put onto an Ipod. But again I don't think the trac info would be transferred along with the song file--even if you type it in to the Itunes library. But I'm not certain.
If you still have your PC you probably have some conversion options that I don't know about.
But 50 CDs is really not very many. I would use Itunes to rip a few of them to your MacMini in AIFF format (same as WAV but with TAGs). Once you have a few CDs ripped to AIFF experiment with playing the tracks in other formats and with downloading various formats to the Ipod. Then decide which you prefer.
