My Tour contact list is empty
It used to have over 6K of contacts
It wont allow me to add a single contact
Won't synch with Desktop (Mac)

What happens when you try to add a contact? Does the contact appear to add, but never show up on the device? If so, your contacts may simply be filtered. In the Address Book, press Menu, select Filter, and uncheck any box that is checked.
