Need help with Cisco 3800 + Cisco ASA 5540 configuration

Hello gurus,

I need some help with a new project. I've never used Cisco ASA before, and I don't know how to set this up.

I have Cisco 3800, with interface gigabitethernet 0/0 configured with private IP for LAN, 0/1 configured with public IP.

ISP tells me that 0/1 (public IP) is to be plugged into one of the 4 ethernet ports in the ASA 5540. I assume I can configure one of these ports for this, but I don't know how to do it. So my questions are,

1) Do I use a cross-over cable to connect router 0/1 to asa port? 2) How do I configure the port in the asa 5540? Do I assign it an internal IP, and set up NAT in the firewall itself?

Thanks very much for any help.

EJ

More Info: I should have included that the 3800 is to connect to the Internet, and the ASA 5540 is to connect to a switch, and to protect one LAN. No other devices or networks.
