I can only suggest you to rip it to mp3 using Lame encoder at high quality settings.
I don't see the point in listening to FLAC audio on an iPod, since the sound quality of an iPod isn't exactly the same as a Bang&Olufsen system.
Actually I don't think the difference would be noticeable.
It also depends on what headphones you use. I can definitely hear a difference between the mp3 rip I did in 192 kbps and the flac. But then again 192 is not an extremely high bitrate. But I usually prefer ogg vorbis. It tends to sound better than an mp3 of the same file size so I'm gonna try that next.
