I would do that too. Get MemOpt and it should clear up everything not clear in the PR book. The PR course is really cool though, like your own personal seminar but you can "get it" with the book, it just takes longer.
The PR course and book doesn't really get into WHY it does what it does and to me that's really too bad because I think most people are getting results but they just can't see the subtle changes at first and they simply don't believe anything is happening so they quit before they even get going.
