just after you created the licorice rep insert a:

mol material Transparent

and all successive representations will use the Transparent
material (or use Glass, Glossy, etc). to make your molecule
look better, you may want to use

mol material Glossy

for the licorice rep.

the color should actually work but it seems that
mol modrep uses the current color state (and material)
so you need to update those every time you update the rep.
also note that only the follwing gives a solid surface.
if you change the last number to an 1.0, you'll get a wireframe.

mol representation IsoSurface -0.02 0.0 0.0 0.0
mol addrep top

you should get a nice solid transparent surface.

please try the attached modified version of the script.
