Ian, I sent this to the list a couple months ago--maybe it might help?  
I don't know that it complete answers your questions, but could be a 
tool to assist in your decision:

*Overhangs and Shading*

A properly designed passive solar home keeps out 
the sun in the middle of summer. For a graphic 
representation of the shade patterns that a
south overhang will make on your south wall 
today (or any other day), check out the 
animation on this web site:
