I think Scot's research is something that you'll continue to go back to as you progress through different stages of T206 collecting. Similar to Bill Heitman's "The Monster," Scot's book has been very helpful for identifying what backs are possible with each front. I believe that's important for a new collector.
On this board certain folks are still updating, negating, and confirming past theories and there continues to be discussion about the printing process, color errors, variations, advertising, etc. If you do some extensive searching here by using the "match" option you can find some pretty good discussion.
Good luck with T206.
Rob
