Post install dual-head nouveau setup?

Played with this some more today, and successfully got both heads active 
(thanks). There are still quite a few "warts" however.

1- My main display is a 42" HDTV (1080p) that runs at 1920x1080. X 
however wants to start at 1080i. I can manually set it, but it did not 
want to start up right without an xorg.conf.

2- How and where is the ability to write out an xorg.conf with the 
current settings?

3- Where is the "Individual Desktop" setting? Bonus points if you can 
add a second Keyboard and Mouse for the second head and *not* allow 
either pointer to the other head.

4- Running a 3D game (which did start up, btw!) and exiting the game 
results in the second head being deactivated, and everything squished 
into the primary display, and off center to the right in my case by 
about 1/4 screen (second head is "LeftOf" primary). It can be 
reactivated by manually running xrandr with all the options, but 
shouldn't it just go back to the previous (default) settings?

This is all on F13 RC, if I should move this to users@, please let me know.
