This is how I would skin this cat ;) Run Ethernet between your two gateway routers, then make them IBGP peers. Have have your other routers connected to both gateway routers. Your 3600, and 2600's should then do per-dest load balancing for their default route. The smaller routers send their traffic to on of the gateway routers, then allow the gateway routers decide between themself which is the best route out. You may not always get the most optaimal route (one extra hop), but it will work and will save you from have to buy another router, and setting your self up for a Single Point of Failure.
We are about to add a second gateway router ourself and this is the way we are going, until we can push IBGP futher into our core.
