You can reuse the ShaderChunk (and therefore reduce the number of state
changes), but you have to have a separate ChunkMaterial (which is what
the VRML loader creates anyway). You just have to add the Shader and
ShaderParameter chunks to the materials in the scene and you should be
fine.
This also answers your second question: uniforms are set using a
separate ShaderParameter chunk. This allows you to use the same Shader
chunk with as many parameter settings as you want.
Hope it helps
