For mac, you can make LW set so iTunes auto imports the songs. See Settings within LimeWire & iTunes for auto import ... If you wish to transfer them to iPod, then I'd recommend manual updating of iPod, see How to transfer music to my iPod (& iTunes) {click on link}. See last post on page I think that has a sample image and video about how to manually update iPod. Check all the iTunes tutorial videos on that page.
