Eureka moment while reading other responses and browsing tutorials
resulted in the attached output from above and below. The ring color map
was generated by a quick perl script I wrote to pull the colors from one
image and the alpha from a paired image, both from
http://planetpixelemporium.com. The planet imagemapped image also came
from there.
I have not tried scaling the planet and rings to proper scales yet, but
should be managable with the notes others have provided here.
