[This is based mainly on the verses of the Old Testament about the kings of Edom mentioned in Genesis.]
The main place to learn this is in the עץ חיים or מבוא שערים.
[I should mention that the Gra held highly with the Ari.]
The major thing to learn in the Ari is the Tree of Life. In terms of the intentions I have found the best thing is the large sidur of the grandson of the Reshash. If one does not have that, then the best in the small set of the Sidur HaReshash. Both are good but the large sidur is more thorough. [The small one is actually a version not directly from the Reshash himself.]
