Yes.

OK.  So the router uses 192.168.1.x, subnet 255.255.255.0, and I can continue 
to use 192.168.01x (same subnet) for the lan?  But the router uses dhcp for 
internet traffic (e.g. the computer I am currently using is IP 192.168.0.3 
for the lan and 192.168.1.64 for the router (assigned by the router's dhcp).  
Would I need to configure the remaining NIC with two IPs?  Should I disable 
the router's DHCP server and configure it to use the existing lan IPs for 
internet connections?  Figuring out how to do that is where I am stuck.

That part I can do.
