I never can remember all of the config files involved in admin work,
that's why I'm becomming a GUI weenie:)  There are several files, as
mentioned, "routed" "static-routes", "network", and maybe some others
that may or may not need editing.  You should find them in
"/etc/sysconfig".  I suggested "netcfg" cause if your on RH, or a
derivative (ie Mandrake like me), it'll be available and will get all of
the files for you.

Your table looks pretty good now except for the duplicate default
(0.0.0.0).  If your using netcfg on the routing window enter your
default route as 65.10.71.198 on device eth0.  This relates to "GATEWAY"
and "GATEWAYDEV" in the file "network".

Here's 1 of my workstations with a similar hardware setup and a couple
of subnets.  I use a NAT device at 10.2.0.3 to get out to the world.
