Hi tigerdude749,
So you've got all your Limewire songs into your iTunes library. Now you have to create a playlist (bottom left, the + button), just drag and drop from your library into the new playlist.
When you click on the playlist, you'll see 'Burn Disc' in the top right corner. Click on the wheel.
Or, you can go to file > burn playlist to disc.

Edit > preferences > advanced > burning will give you some options like speed, type of disc etc.

Hope this helps

Btw...was that sister or cousin? Can't be both
