I myself have a California Air Tools compressor, they are much quieter than the typical air compressor and bought it for that reason.
I currently don’t use any coolant/lubrication, I tried a cheap mister setup once and it just made chips stick, created a nasty fog and required more work to clean up. These days, for chip evacuation I just use my [Suck’it] dust boot with a Home Depot Dustopper, and has been working great [for flat stock]. I do want to revisit the mister setup with an alcohol based mix that is also pressurized (i.e. FogBuster) but isn’t a top priority with the results I get with out already.
I highly recommend single flutes as well, can be more costly but they are more forgiving and less prune to clogging IMO. I have used Carbide 3D’s (ZrN), Amana Tool’s (ZrN), and 2L inc. (PCD) single flutes, all with great success.
