Joe --
A good place to start is T206resource.com, which has all the information you could want to know about T206, and more. The amount of information there can be overwhelming, especially for a beginner, so it's best to start on the index page there:
http://t206resource.com/History.html
You can start on the "Introduction" page and then keep clicking "Next" to go through the pages.
You'll also want to go to the "Publications" page:
http://t206resource.com/Publications.html
There you can download pdf versions of three booklets that serve as good general introductions to T206: Art Martineau and Doug Allen's (unpublished) "T206: The First Century", Mark Peavey's "The Mysteries of T206", and Scot Reader's "Inside T206". Peavey and Reader are Net54 members, and Doug Allen used to be a member but is in jail now.
The "Articles" page on T206Resource.com has lots of good articles on various aspects of the set. Most of them are for people who already know the basics, but there are some more basic introductions.
