What you are planning to do sounds pretty solid.
Now, if I were to do it again I would do the following:
1) Pull out PREP questions from the last 3-4 years that had to do with ID (I think there was a simple way to do it with the CD's).
2) I probably would have read through the ID chapter in Zitelli's. The text seemed to give a good overview from a diagnostic standpoint.
Otherwise, I wouldn't do much more. Granted, I went to a small program, but I remember most of the ID consultations consisted of first line Abx choices before the C & S came back, or alternate choices when the bug was resistant to pretty much everything (which is why I think reading the lippincot chapter is a good idea).
