I hope as user I could also make suggestions and say what I think ;)

for sun and Hemi Lamps you could make the Backfaces Invisible for lightrays.
For Preview, I would as user prefer to use the Current Cycles settings 
so I have the exact preview for the material. (If I have OSL materials 
they go Black if OSL not active)
