Jason,
Are the two routers directly connected? I believe that BGP neighbors need
to be directly connected. This is the end of your show bgp neighbors
command:
External BGP neighbor not directly connected.
No active TCP connection
I think that this is saying that your two routers are not directly
connected. Therefor you are not making a TCP connection with BGP even though
you have IP connectivity.

Do anyone have some BGP "show ip bgp neighbor" or "show ip bgp summary"
outputs between two ASs that are talking ?
I have two routers connected but am not sure what the "show ip bgp summary"
should show ? I can ping both ways, etc....
