Keep lights on their own circuits, don't share
neutral or ground wires, make sure the neutrals
and grounds of lights are as long as possible
before they connect to audio neutrals and
grounds.
A venue wanted dimmers for lights. The solid
state dimmers were really expensive for the
power required by the lamps. I found some
surplus autotransformers that worked great
for dimming, cost much less than the solid
state dimmers, and presented no noise on the
hots, returns, or grounds.

signal and data for

It would be wise to complete the engineering before going further
with construction. Even if you are an electrical engineer,
electronics technician,
and/or electrician, you might want to get a second set of eyes
checking your designs.
That will happen anyway, but I would agree. I will not be running the
wire or doing the install. But I do have input.
I will do
a second for stage lighting as well, if for no other reason
than keeping the audio power from being used for lights :)
It is wise to put lighting on it's own feeder and panelboard.
