That sounds like a good plan! In reviewing my highlighting in her book, it touches on quite a bit of ground. For example just in my first couple of highlights she touched on the pleasure/absence of pain controversy, which got me thinking about some of the issues involved in that debate. I don't recall if she goes in depth into that issue or not, but I'm getting the sense that there are endless topics for discussion in the book.
I think that's one reason why I remember so little of it other than general ideas. As you suggest Don you might be better served to begin with the original text and then dig into secondary discussion of it....
