Hey, I've only made weapon models in the past, and I want to make some props as well . So my question is, What do I name the parent root for a prop and where do I place the prop in coordination with the root. Thank's in advance .

Doesn't matter, you don't need a root.

But it sure does halp keep things organized especially when it comes to exporting to msh it is easier to branch select the dummyroot.
It is just a null that all your model bits sit under.

That makes things easy . Thank's.
