The difference, I think, is because network-manager is handling the wlan0
interface, and not handling the eth0 interface.  

The reason though that the DNS settings change is that dhcp is configured
(in /etc/dhcp3/dhclient.conf) to ask for a DNS setting (request
subnet-mask ... domain-name-servers).  If you remove
the "domain-name-servers" parameter, it should leave your settings alone. 
I believe that for eth0, currently, you're getting the 192.168.0.1 value
back from the router, _then_ overriding it with the value
in /etc/network/interfaces.

otoh, it doesn't seem right that using your local DNS cache on the router
should cause problems.
