1. Nope. Not a simple object.
You could try and construct your object with Christoph Hormanns
isoCSG, and try to blob the edges away a little, I've never done so
and don't have any experience with it, so I'm not even sure if
it'll work. But that's the only idea I can come up with, aside of modelling
with some other program than POV-Ray.

2. Light, shadows and surfaces
Well, for the light & shadows, use area_lights, fade_power, radiosity
and photons, and you've covered pretty much every realistic
effect possible (though nothing that resembles effects occuring with
different wavelengths, like bending around corners and such...).
For the sharpness of the image, look at focal blur, which covers
you're photographic "everything sharp" problem.

For surfaces, well, you've got to learn all tids and bits about finish,
normals and textures, but mostly probably about normals and
finishes, like reflections, brilliance, specular highlighting, fresnel
etc...
