I do not use Corona but generally (across various material types and renderers), for the height map you have a choice of the Additional Bump slot in the Normal map you are using or the Displace slot. Using the Additional Bump slot will be a more subtle lighting effect simulating a bump while the Displacement slot will actually displace the geometry during the render at the expense of a longer render time. You will likely need to play with the amount of additional bump or displacement to get the optimal look for your purposes. Try rendering with each and without using the height map at all since the normal map will also create the illusion of raised and recessed areas.
Regarding the more general request for an explanation of various map type assignments, there is a video tutorial series on the Corona Physical Material which looks like it will give you a good understanding:
