Looking good!

You can do this by calculating the dot product of the shading normal and the up vector.
(the power operation is just used here to enhance the contrast)

I'd say the user should use white light. Then the light groups can be colored with a simple multiply operation.

I think it's only the light brigthness that's off. Should get fixed if you use the "convert to 2.3" button in LuxCore tools panel.

1) Texture animation key frames don't show up in the Graph or the Dope Shee (or anywhere)t. I believe I have determined (by lots of reading) that this is isn't supported by Blender with certain plugins. Is that correct or I am missing something in my studies? Correct, this is a limitation/bug in Bl...

Mirroring probably makes all normals point in the other direction. Some LuxCore materials act differently depending if it's a backface or frontface, e.g. glossy is only specular on the frontface, but behaves like matte on the backface (https://github.com/LuxCoreRender/LuxCore/issues/301). You should...

Filesaver won't help you investigate shapes anyway, it only saves the end result mesh of the shape evaluation.
I would recommend to check the LuxCore samples, the LuxCore shape source code and the BlendLuxCore implementation instead.

In the render properties, LuxCore Tools panel, enable "FileSaver" and choose text format. Then render with F12.

1 Blender Unit = 1 meter in LuxCore.
Just like in Cycles, unit scale is ignored. So if you want parameters like f-stop in depth of field to work exactly like expected, use 1 Blender Unit = 1 meter. Otherwise you will have to do the conversion yourself.
