Now how do I relate candle/meter^2 measures to monitor target values?
Candelas per meter square IS the monitor target value; which is related to suggested ambient light levels (or ambient light levels are related to suggested target monitor values, you can adjust either).
Using 5000k lights and calibrating to 5000k will not solve the issue: lots of 5000k ambient light would still require a monitor temperature of 6500k, since it would stimulate the rods less and the cones. A tiny amount of 6500k ambient light would require you calibrate the monitor to 5000k. Do you begin to see that monitor temperature and ambient light temperature are unrelated items? The eye is variable in how it perceives color, so the monitor must be adjusted for that, not the color of that light.
