Not sure if this is the right spot...transferring contacts?

What phone did you come from before the Touch?  I always suggest that Verizon customers take advantage of the Backup Assistant app available for free from Verizon as long as you have an online account.  It can automatically update the system with any changes you make to your contacts on a schedule that you set and then when you upgrade to a new phone for whatever reason, you can just download the same program to the new phone and it loads your contacts nice and quick. 

I know that doesn't really answer your question about syncing your contacts from your Mac but if you still have your old phone, you could reactivate it, download the BA app, save your contacts to their system, and then reactivate your Touch and be done.  You can take care of it online or just call customer service from a third phone and have them walk you through it.
