Z in a positive direction should always be up on a 3-axis machine --- the only time it might even appear not would be if the machine was already even higher than that position.
One would think so, but apparently it varies between manufacturers. Our machines are all carving up a flat surface resting on a table. I think what's going on is that functionally that means that the working head is permanently upside-down. Is Z measured in the context of the whole machine, or is Z measured in the context of the cutting assembly?
