Newbie question, routing between two 3620's

We have two 3620s, each with 2 WIC (2 slots, and 2 10BASET jacks) each WIC has a pair of single T1 cards. So we have 4 T1 WAN connections, and

4 10BaseT connections.

We have a pair of T1 lines between the office, and the NOC, which we want to stretch our office lan across, so that everyone in the office can have internet access, and the dev machines in the office can also directly access the backend machines in the noc, but the office machines can only access internet.

I currently have the dev machines on 192.168.100.x and the office machines on .200.x, works well for the internet access, NATing across the serial link. With one LAN port at the noc connected to a public routable IP, which is serving as the NAT pipe for net connectivity. But how can I selectively route the .100.x traffic to the 192.168.10.x machines in the backbone (the other LAN port on that WIC), whilst NATing them out to the net across the other LAN connection for internet access?

Thanks for any help.

After this, is figuring out how to bind the two T1 links together for bandwidth...

You should only do NAT on the port connected to the public IP, you shouldn't need to do NAT between any of your internal networks. NAT only takes place when a packet is going between an interface marked "ip nat inside" and an interface marked "ip nat outside". When it goes inside-to-inside, no NAT is performed.
