As the simplest answer, set up a L3 link between them and let your routing protocol handle it.
But there are some other basic considerations as well. Are there other subnets at each site that shouldn't pass over this link? How does your routing work now? Can those switches handle any QoS that you want to use?
A lot of this is my fault, it was all last minute today and I didn't get enough information from the customer. Guess it will be tomorrow but I think I have a handle on it now..I stepped back and thought about it and it makes sense, if it is truly L2 then AT&T would have to handoff at Site B, otherwise I need to get IP's from them then I will use EIGRP to route the appropirate traffic across.
