Roy,
I like your list, but would remove Dr. Glover's book for now. When his new book is published, I believe he will have weeded out some of the made-up parts that he received from a "trusted source". Despite that, I believe his book is one of the best ever written on the history of Jacob Waltz and the LDM. His research into the verifiable history of Jacob Waltz and the information he received from other sources is some of the best.
I would add "Tales of the Superstitions" by Robert Blair to the mix for #5.
I would also add "Superstition Wilderness Trails West", "Hiker's Guide to the Superstition Wilderness" and "Superstition Wilderness Trails East" by Jack Carlson and Elizabeth Stewart. While the last three are not LDM books (but very close) per se, I believe they should be required reading for every Dutch Hunter, and hiker, who explores the interior of the Superstitions.
Take care,
Joe
