I agree and disagree with some of your stuff:

General
 * First off, Aura is very similar to a lot of other soul-based abilities I have seen in a lot of other shows. The concept of Aura, Ki, Chi, or the other 50 names people call it doesn't appear much in American TV, so if you don't watch any anime I can see the mistake.
 * I don't agree that Grimm are dead/undead. They may not have a soul, but apparently some branches of Christianity don't believe animals have souls either. That doesn't make them dead, just soulless.
 * I do agree that there is some kind of being that created the Grimm. They had to come from somewhere.

Dust
 * I agree that Dust may have been around from the beginning. Humans just didn't know how to use it until they fought the Grimm.
 * I agree Dust and Aura aren't related. Dust is an energy source, Aura comes from life force.
 * I think Dust replaces oil and coal in this universe.

Fauna/Fanus/Fauni
 * I disagree.
