This is the end of the crankshaft where the timing pinion goes. Is it sitting correctly? There is a portion of the plain shaft protruding which looks like it should maybe have a spacer on it?

The timing side crankshaft bush has been replaced and honed but there don't appear to be any oil holes in it. Is this correct or should it be drilled?

The P bracket fits to your Q gearbox( 2 holes) and the other hole is for the frame bolt. There is a spacer behind that bracket to frame.
The pinion gear requires no spacer and is located by a wood-ruff key
The bushing look normal to me .the groove allows oil to flow through

The grooves in the top are in the right place to feed oil into the two bearings. You are showing the later timing gears which fit OK without any modification. The small gear should be a reasonably tight fit on the straight section but not so tight as to make it hard to tap on when the crank is in place . Nev

I've just checked a 1930 crankcase and there's an oil hole drilled from where the camshaft just clears the mainbearing extended boss into the bush.. Its countersunk a bit at the top end.. It's about 1/3rd of the way along the bush from the end where the timing gears go. Otherwise your oil grooves are correct. Nev

Got another question:

I want to buy a complete close ratio gearset but does anyone know if this includes the mainshaft?

Cheers
