Comparing a neutral grey on screen to one on paper (color chip from XRite) the grey looks very warm and no where near neutral.
Unless your lighting is D65, that tells you nothing about the quality of the monitor profile. Similarly, unless they're the same grey, you're just grasping at straws. D65 will look warm to most users, as it's still fairly common for consumer-level displays to ship configured for an extremely blue ("white") picture. If native looks better, try working with native.
I noticed through playing with luminance, that the Colormunki basically ignores the contrast setting.
Correct. You can't adjust contrast on an TFT LCD; it's a function of the backlight brightness and the design of the panel. Your "contrast" OSD adjustment just munges the incoming signal to flub some facsimile of contrast control. It shouldn't be adjusted under normal circumstances.
Playing with luminance, setting the brightness setting I had trouble hitting the "green point".
The green point is more trouble than it's worth; different situations yield different luminance requirements. While getting in the neighborhood of the green zone is a good starting point, you're likely going to end up using a different number in the end. One that gets a good screen-to-print match for you.
Next there is an absolute lack of RGB calibrating. Before and after calibrating, MY RGB settings are the same, 100/100/100.
They should be. See contrast above. There is no adjustment of the RGB guns because there are no RGB guns—it's a lame facsimile in software that mutilates the incoming signal. You do not want to adjust the RGB settings under normal circumstances (hence the Colormunki correctly not asking you to adjust them).
