Could you please provide some type of diagram with what you have setup, i see that you have some ibgp connections. Also what IP ranges do you want to be available during this fail over.

I would highly recommend removing the diagram since it contains vital data for your infra.

From looking at your diagram i assume your web servers are in the DMZ that is behind your firewalls.  There are ways to do this, you will need to either do IBGP peering between your external routers or redistribute to a IGP and use that between your BGP routers. You will have some issues with bandwidth because if you advertise the 64.83.86.x range out Dallas then in order for that traffic to get to the web server it will need to go use your internal network links, witch could use all of your DS3's.
