Sorry but I find most of these quotes rather disappointing. There's a big difference between rules knowledge and major flaws in etiquette and the fact that it's his first comp doesn't automatically assume that he won't be clued up on the latter and won't endanger your own round from an advice point of view. He's not asking for help on technique or club selection.
With clubs desperate for new members, and those joining wanting to get involved in all aspects including comps, they need to be encouraged rather than put off for good by somewhat narrow minded standpoints and generalist assumptions. We all had to start competitive play somewhere and I would wager the vast majority only had a basic, and probably not entirely accurate, understanding of the rules at that point. You only learn by experience and asking questions.
I say to the OP ignore the rather negative vibe of this thread, go out and enjoy it. Expect to be nervous, expect to make a few bad shots and even score badly. Get the first one out of the way and it does get easier over time
