total timing reading accurate with no load?

Got my plate and the 2 silver medium springs installed. I put in plate as suggested, on the 18 slots. After warmed up with no vacuum advance my initial is at 16 and at 3200rpm+ it stays at 34 degrees. Engine seems really happy with it.

I then played with the vacuum pod hooked to manifold vacuum, (had to 'customize' an allen wrench to fit past the oil pressure sensor) and after SEVERAL counter clockwise turns I was able to achieve 30 degrees at idle (originally was at 40 with vacuum). Rechecked initial and mechanical with vacuum unplugged and they were same at 16 and 34. Hooking everything back up and then test driving.

2 Questions:
What should I have my idle speed set at with these new settings?
My full mechanical advance doesn't reach 34 degrees until about 3100rpm. Is that too high? I'd rather not go through the hassle of replacing springs again if this is acceptable.
