One more tip, when going for the checkride, make sure your PTS is worn out, dog-earned, pages bent, and generally looking very well used. The same with the FOI.
The best way to get the well-read look to those books is by reading them, studying them, and getting a good working knowledge of them. Handing them to your dog won't work as the examiners can see right through teeth marks, unless they are your own.
How's the studying coming along?
