I think I'll remove the second moon and play around with the scale of the  
planets. Hmm, I like planet rings, but the realistic option would be more  
like Avatar's Pandora and I wouldn't want to copy... ;)
Maybe I should take the planets even further apart, and add thicker  
atmospheres to both planets, so that it becomes a mixture of terrestrial  
and gas planet? Do you think there is a viable way to make a figure 8  
ringed binary system work or at least seem more realistic? Hmm... I  
remember Grey Knight worked it all out long ago on this group and came to  
the conclusion that there would be a "ring-storm" every 13-years if the  
planets were the size of earth and they were as far apart from each other  
as the moon is from the earth...

BTW the rings are discs, so in this case they _are_ infinitely thin. The  
sun is at a slight angle which is why you can see the shadow.
