I've heard the book is complicated and difficult to understand without further certification or instruction. I'm a 2 handicap and think I have a fairly good understanding of the swing. Will I be able to get much out of the book, or should I not confuse myself with it and just find a TGM teacher instead?

The book ALONE will be a tough nut to understanding especially if you know something about the swing because a few old truths will no longer apply.
