frustrating xorg.conf setup with nv driver

[Neil Short]

Would you mind helping me to get this thing working
with dual monitors? I
prefer that both monitors show the same thing; but if
the external is
adjacent, that's fine too. All I have been able to
accomplish is to keep
the built-in monitor looking good and the external
looking like rubbish.

Thank you for looking:

Below are the details of my setup:

Computer: HP Pavilion zv5000
card: Nvidia
res: 1280x800
external monitor: vanilla standard resolution: 800x600
or 1024x768

xorg.conf file that works on the built-in screen:
