Thanks.  I have a) taken care of.  See http://monoport.com/17516

As for the monitors, I wanted to make things as simple as possible in 
order to narrow this down.  So I configure and use only one monitor at 
at time, the projector is the only thing connected to my computer 
currently and is the only output I have configured for this at the 
moment.  I did a clean configuration for the computer monitor separately 
and got that working only once, temporarily and I haven't been able to 
get that working again either.  I'm also using either the VGA out for 
the monitor or the DVI out for the projector but not the TV out in 
either case.

Thanks for your suggestions, any other ideas?
