The race order should be in that rule/guide book you said you were working on along with stuff like: Resort Round(s), Tie Breakers, Controlled practice length, Race length, Main starting method, Time between Rounds, Time between races, Drivers minute allowance, Qualifier starting method, when drivers are allowed on the stand, Scoring system setup, etc.. My personal opinion is the only thing that should be different at each event is the Location and Track -- Everything else should be run the same from race to race.
Not to mention information given to tracks on what is expected of them. I personally feel tracks should be required to have a fresh track that no one has run on - if that is not the case that's fine, but all the tracks should know whats expected.
