Yay, I have managed to get my drivers installed and working.
The process on the following thread is what I did to get it working (on page 3):
Specifically I think it was:
3. uninstall in synaptic nvidia kernel common. Do a search. apply the changes before exiting synaptic
It may also have had something to do with:
1. fix software sources "Download from" usa to main server. update the resources. It is in Administration->Software Sources.
Although there may have been more to it than that.
Thanks a tonne NVidia for your Linux Support!
