Sorry, I assumed dhcp...

For the upstream dns servers: I've never used NM with dnsmasq,
resolvconf, and a static ip address! I would've liked to test the
following before posting but I don't have an Ubuntu box available
right now. NM runs its own version of dnsmasq and, AFAIK, picks up its
config from "/etc/NetworkManager/dnsmasq.d/". dnsmasq has a "server="
configuration option so you could set that to an upstream dns server.
Make sure that you chmod the file to 0600 or 0700 because NM usually's
strict about file modes.

For the default gateway: Have you checked the ipv4 settings in the NM
applet? If you choose static, you have to enter ip address, netmask,
and *gateway*.
