In the instrument flying handbook, they go over the approaches in a generalized way. For example, on page 7-33, they talk about the function of an ILS and how to maintain heading etc. I'm taking my CFII ride this week too, and I'm reviewing this book almost exclusively.
I wonder why your examiner is making you do lesson plans for the addition of an instrument rating to a CFI certificate. The area of operation (IV) Preflight lesson on a maneuver to be performed in flight is marked with a N for not required.
