3) Do I need the shutoff valve in front of the QC3? I already have a quick disconnect to take the compressor out of the system and can let the air out of the drain if I need to de-pressurize and change the QC3 filter. It just makes the whole setup wider and I'm cramped for space.
Thanks!

Too many Regulators.
I can see the use of two one on compressor to control 90 psi out put through out shop and another after Qc3 drier for paint booth and that's it. each will limit air flow and that's bad. also keep in mind NOT all regulators are Hi flow regulators! Painting requires very hi cfm flow requirements that not all Regulators are capable of.
I do not have one at all on my compressor outlet at all, My manifold is plumbed open system unregulated through out my shop to my filter bank and and my one and only regulator after my DAD500 filter bank and drier assembly with a Hi flo Regulator specifically for Painting.
Yes I have a Ball valve in front of my filter bank and drier assembly that I shut off when I am not painting so my Drier doesn't try to dry entire system from the inlet. a Desiccant drier will try to do that and the media would get saturated leaving it worthless.
In my case If I have a tool that absolutely needs regulated air for a Tap off my manifold such as my Glass bead cabinet I have one on its inlet dedicated for that air Tap only.
For my Impact and Air drills Die grinders and such they are run off of full unregulated manifold pressure unregulated and have never had a problem.
Now my Nail guns and Air Staple guns they get regulated air pressure and here again I use a regulator that I just plug into the manifold with quick disconnect fittings as necessary to dial down pressure and can move it around shop were its needed.
Some Air tools will not like unregulated air pressure so like I said using a regulator I can move around and just plug in as required is beneficial for me others may have different opinions, just what works for me.
