Clarification for short story.

I'd let my hands just write what they wanted, and I got a 3 paragraph-
long snippet of a story. The trouble with is that I'm not dead certain
about how accurate my terminology is.

1) A "priest" or "upper-classman" was a *bhlaghman, right? How many
were there for the average group of PIEans?

2) Since *dei- is the root for "god" and "shining," wouldn't *Deiaus
P@... literally be the "Shining Father"? And might he then be a very
old Sun-god? I know there was another god for the sun, but mightn't
*Deiaus P@... have been a sun god antedating the other one?

3) To say "I believe in you / I put my heart in you, Deiaus P@...,"
would it be "Egh kerd-dhe, Deiaus P@..." ?
