Sorry if I'm adding redundant info here. I haven't gone through the entire thread.
I'm guessing you also have external drives in the mix for media? Have you tried hiding them from spotlight?
That seems to have fixed the exact same issue on my new rig. If you use a dedicated media management database and don't need spotlight to search those drives it might do the trick. Spotlight doesn't seem to let go when you are ready to shut down.
System Preferences > Spotlight > Privacy
Volumes you don't need finder level search capabilities on can be draged into that window and spotlight will leave them alone.
Worked for me.
