Hello, 

  1. I was wondering how I can get that average value

You can use the measurement feature and create an area projected on the shape you will be able to get the average on this area.

2. which of the ambient sources most accurately simulate the sky

The more complete sources are CIE Standard General Sky and Natural Light

3. is there a way to isolate just the sun using any of the ambient sources

Yes, you can use a "natural light" source and put the "with sky" option to false

4. is there a way to know where the sun is located or the direction of the sun.

The sun position is represented in the 3D view (the yellow circles below)

 

Best regards

Thomas
