Good selection. I'd add Shobogenzo by Dogen for a deeper look into the Zen craziness designed to break patterns. And Matthiessen's Nine-headed Dragon River is both a personal history of Zen in the US and a memoir of his wife's death. Finally, for a buddhist view from the Tibetan tradition, Reflections In A Mountain Lake by Ani Tenzin Palmo. It's remarkable. Btw, I live across the street from the Rochester Zen Center which Kapleau founded and was one of the first in the US. They have a beautiful Japanese garden that I meditate in.
