All of the calibration guides I've seen suggest using a piece of paper (0.1mm) as a feeler gauge.
This would mean that when you issue X0 Y0 Z0 it will actually be X0 Y0 Z0.1 should I be subtracting out that 0.1mm so that the hotend is actually at Z=0?
Seems to me that if I don't the Slicer will make a 0.2mm layer 1 at 0.3mm in height.

You are correct. I use a piece of stock that is 19mm to set my zero, it could just as easily be 12.3765mm or any arbitrary number. I have fine jog buttons setup so that I can move .01mm at a step. I move the head to where I think is Z19 (or a little below) and then jog up until I can slide the shim between the head and the bed. If you don't have other means (tool and work probe etc etc) this is the best way to set Z0 in a mill too, jog UP until a shim clears, avoids running into the work or part. Avoids chipped tools, or in our case dented nozzles or beds. I then issue G92 Z19.0, setting the Z at that point to be 19.0 When I measure the thickness of that first layer it's what I expect it to be from the program. If the shim piece is different thickness you use that number instead of 19.
