Stretch,

You have found some good sources. Also being in Holland, you should look at Vermeer's paintings (and other Dutch masters). Their painting technique was unbelievably complex. The painting looks radically different close up then when you look at the whole picture. Rembrandt seems to be the most complex. Go to the nearest museum and get as close as they would allow you (in the Cleveland Museum of Art, they do let you get very close) and notice the complex structure of the these paintings.

Then I would do what these articles suggest. Experiment and observe. That is how I learned. Looking at tens of thousands of test panels over the years is what worked. I never had a textbook to turn to learn how this works.
