So to answer the second question, there is currently an experimental X3D 
output option that is only available on the command line with the x3dsave 
command.  X3D is the immediate successor to VRML.  Chimera outputs the XML 
version of X3D, so you can use various XML translation tools to convert it 
to your prefered format.  All of the geometry is in the X3D file.  FYI, 
there appears to be a bug with non-flat ribbons, but everything else 
should work.
