Tim,
Unfortunately, you can't plug an ipod into a USB DAC. It won't work. You can plug your computer into the USB DAC though.
Yes, EAC is for ripping CD's to files on your computer. Search for some tutorials on how to set it up for FLAC. Once you have your CD's backed up on your computer in a lossless format (FLAC), then use DB Poweramp to convert the files to a lossy codec for your ipod (mp3, AAC). Or you can simply rip the CD's using Itunes using Apple Lossless if you want to use lossless files on your ipod. Takes up more space though.
