Help with my xorg.conf for video resolution

[7echno7im]

Hello. I am having some minor issues with my xorg.conf. I have kubuntu working rather well except my xorg.conf.

Hardware: (pertaining to my question)
video: nvidia 7900GS
display: Dual (2) Dell 2005FPW digital conX
native resolution for each: 1680x1050 32-bit color @ 60hz

What does work:
Dual monitors, decent display, 3D rendering, nvidia driver, beryl

My complaint/issue:
In the display config, the resolution is at 3300x* something and I cannot change it
When I apply desktop backgrounds, they do not stretch correctly
when maximizing some windows they do not stretch correctly until i click on them, then they *snap* to full screen

I know this all is related to my xorg.conf, so hopelly there is someone who can look at it and help me out. I want to configure it the most efficient way, excluding any resolutions less than optimal.

Thanks in Advance,
7im
