well, very quiet here….

It's unclear how you plan to connect to the H8000.

AES would probably be best (ADAT limits you to 48k at 8 channels), with a WordClock sync source. Until we know this, we can't advise about routing.

I would also lightly suggest that you appear to be planning a complex system, and if as you say, you are not really tech-y, you might want to consider some local technical help.
