Interesting review. Being more into the Early Henrician period, I am - almost inevitably - very disappointed with books on "Tudor Warfare" as they (a) never seem to really cover my period of interest (the invasion of France/Flodden campaigns), and (b) always focus much more - and with far more references - on the later era and especially Elizabeth. As such, I bought Volume 1 more in hope than expectation and was not planning on bothering with Volumes 2 and 3. However, your review may have persuaded me to change my mind.....
As regards a possible landing by the Armada forces, something that is often overlooked (and I would be interested to know if this volume considers it) is that the Spanish embarked very little cavalry, and that all ginettes-type light horse. I can't help wondering what may have happened to any Spanish force landed in, say, Kent, if it's recce/scouting(/looting!) capability had been totally destroyed by a demi-lancer/reiver combo, leaving the infantry unable to "see" beyond the ground they physically occupied. And of course, once deprived of its scouting/foraging arm, how far from the coast could the infantry have advanced with nobody to protect their logistics? Did the Armada land commanders perhaps think that the "weak and feeble woman" in charge would just have given up once they landed?
