Hi Michael,
Syncing contacts to an iPod classic is explained in this article -
iTunes 11 for Mac: Sync contacts, calendars, and other info with iPod, iPhone, or iPad
http://support.apple.com/kb/PH12117
Specifically -
Sync contacts and other info with iPod nano or iPod classic
- Connect your iPod to your computer and select your device.
- Select Sync, and then select options.
Your contact and calendar information is updated on your iPod each time you connect it to your computer. You can also update your information anytime your device is connected by choosing File > Sync iPod in iTunes.
If you have problems syncing, try syncing only certain information. For example, deselect the Sync checkboxes on the Music, Photos, Podcasts, and Video panes, and try syncing only Info.
Thanks for using Apple Support Communities.
Best,
Brett L
