If it works for you, it's a good way. Just wondering how you turn off
the shadow on second image: with +Qx (x <4), it also turns off patterned
texture, extended light, photons, refracted & transmitted rays and
media, radiosity and sslt.

For the shadow only image, you might want to have a look at the no_image
(and maybe no_reflection) as object modifier.

For the objects without shadow, there is the no_shadow object modifier.

You could use the animation subsystem and a macro like

#macro WHATPART()
#if (clock > 0)
 no_image
#else
 no_shadow
#end
#end

with your objects calling WHATPART like:

sphere{ center, radius WHATPART() ... }
