Sorry to take so long for the the update. I can't believe the interfaces were shutdown... but over the weekend I retried it and had success in getting the setup exactly how we wanted, which was dot1q over the T1.

According to your "show run" all interfaces on the router are in
shutdown state, so nothing is going to work. One you have interfaces up,
you also need to have working routes at each end to the IP address of
the pseudowire endpoint at the other end.
