Well, the article is a bit off in its presentation regarding modern ideas on what that area of Qumran was. It hasn't been thought of as some hidey-hole for Essenes in decades, and has for quite some time been considered a location that was more a stopping-off point in a journey than anything else.
You seem to continually ascribe lots of importance to the most odd things. I don't mean this as an attack, but as a statement of being confounded by how you're reaching some of the implicative things you've posted.
I'm going to suggest four books that I think would be incredibly helpful for you, but none of them are (specifically) on the subject of the early Christians, the origins of the Jesus story, the gnostic cults, or any esoteric material. I feel so strongly that your reading them would be helpful to you that if you don't think you could find or afford them I will pick them up at my local bookstore and
mail them to you (limited time offer, while supplies last, etc.), whether it's one or all four you think would be acceptable-- or you could very likely find each in your local city library. The four books are
Why People Believe Weird Things and
How We Believe by Michael Shermer,
A Mind of Its Ownby Cordelia Fine, and
The Demon-Haunted World by Carl Sagan. Those four will help you more in finding out what to look for that me offering a library list of books on the subject of Christianity in its infancy, Egyptian or Mesopotamian religions, or me offering treatises on the weaknesses of syncretism.
