I'm sure there are more, those are just the ones floating around in my head right now(that I've actually seen) some have books and DVDs, others, not so much. The only sources from Ricky Jay for example, are a YouTube video of a show, a documentary, and some historical texts. However that performance is a gold mine of information.
With regards to teachers, seek out material by
Roberto giobbi
Joshua jay
Helder guimaeras
Dai Vernon
Juan tamariz
Michael Vincent
Those are the only guys I can personally attest to, however anyone on those lists would be a pretty good bet as a solid learning source. However, at least for now, try and avoid those flashy, modern type guys like shin lim, Daniel madison, Dan and Dave, etc... and focus on the more classical ones like jay, gumaeras, Vernon, etc... Also, meet and talk with fellow magicians in person, attend lectures if you can, or find some knowledgeable magician in the area and at least occasionally, hang out and get some feedback.
