For least noise you need to be carrying your grounds to a single star point,
which then connects to the chassis at a single point. That makes sure
that ground currents can't generate any voltages in the signal path.
Careful ground design allows you to use a single chassis quite
happily.

Exactly as you describe!

Brilliant, then just bolt them together and hard wire the connection.
