I'm running FreeBSD as a gateway for Windows boxes, but the general process 
should be the same for Linux.

For the Media General RR system, you only need to use  the Windows Road Runner 
Manager app to perform account admin functions (setting up sub-accounts, 
mailboxes, etc). I can do that from a Windows machine after I change its DNS 
domain name to mgfairfax.rr.com and reboot. Normally, my Windows machines have 
a DNS domain name entry matching the bogus domain name I've given my private 
network.

For complete Internet access from your Linux box, you should only need to 
install and run a DHCP client so you can obtain a registered ip address for 
that machine. There are at least two clients available, and I think either one 
will work. One or both probably came with your Linux distribution. Read the 
docs and follow the directions. Getting access for the Linux box should be 
pretty straightforward.

Setting up the Linux box as a gateway is more involved. For the newer Linux 
kernels, you use ipchains for Network Address Translation (NAT). You'll also 
want to set up a basic firewall and probably a caching-only DNS server to 
service your private network and forward requests to the RR DNS servers. There 
are Linux HOWTOs and several excellent web sites that cover all these things. 
If you need help finding web sites, drop me an email.

Hope this helps,
Dave Plummer
