It's pretty straightforward. Each of your webservers will have its own address on the PSN (DMZ).
The EXT address of the GNAT Box will have tunnels to connect the ports for the services you want to provide (probably something like 21, 80, and 443) to the primary webserver. For each additional webserver you will create an alias on the EXT interface, create tunnels to connect the ports for the services to the webservers, and create a static mapping from the webserver back to the alias. If you want to allow the entire Internet to access the webservers, then you can check the "filter" box when you create the tunnels. Otherwise, you will need to create filters that control access to ports 21, 80, and 443 (or whatever ports you created tunnels for) on the GNAT Box EXT address and aliases. For email, I would suggest using the SMTP proxy. Fill in the form under "Authorization/Email Proxy", and list all of the domains that you want to receive email for in the "Domain(s) to Accept" field. Any SMTP connection to the GNAT Box EXT address will be proxied to your email server (as long as the domain matches one of the domains that you list - this prevents spammers from bouncing email off your email server). You can cut down on the amount of spam you receive by enabling more of the Realtime Blackhole List (RBL) servers, but be aware that orb has been known to be a little overzealous at trying to block spam, and sometimes blocks legitimate email.
