Answer 1

That is not a way how the WebGL 3D rendering works. All materials will be affected by light. You can render a shadows: http://learningthreejs.com/blog/2012/01/20/casting-shadows/ but, that means the light on the Meshes will be always rendered and after this will be rendered a shadow. That means, if you have a meshPhong material with a high shininess, it will be rendered visible and darkened by the shadow, which is not physically possible in real.
