You can use the ip command to modify the routing tables (and more!) 
pretty easily.

The following should be enough to get rid of the old routes as well as 
adding the correct default (via your router). Getting rid of the link 
local (169.254...) address is not really that important, even a freshly 
installed machine will have it, it just allows machines to communicate 
if your DHCP server is down.

sudo ip route del 64.166.164.54
sudo ip route del 0.0.0.0
sudo ip route add default via 10.0.0.1 dev eth0 metric 0 proto static
