In the case of USWest.net, the eth0-0 interface on the Cisco gets a
10.0.0.1 Ip assigned to it (you can, of course, configure it in a
different way), the wan0-0 interface gets the real routable IP.

Again with USWest.net, your Cisco gets the real IP. In the case of other
ISPs here in Minnesota (like visi.com), they always give you one static
IP. Again in that case, the wan0-0 interface on the Cisco gets the
IP. The eth0-0 interface still gets an internal IP such as 10.0.0.1. It
sounds to me as if your ISP does the same. If that is the case, simply
configure your Linux system with a static IP in the 10.0.0.0 range (such
as 10.0.0.3 or 10.0.0.4), and that should do it.
Your Cisco 675 runs both a DHCP client and a DHCP daemon/server by
default. One of them is to obtain the IP from your ISP, the other to
assign dynamic IPs out of the 10.0.0.0/24 pool to your own
systems. However, the last time I tried the DHCP client in Red Hat Linux
to work with this daemon it failed. That was over a year go
though. Perhaps it will work fine now. That's why I recommend to use an
internal static IP instead.

I believe you're right, but I'd recommend to talk to your ISP's tech
support group since everything depends on how they configure their
routers.
