Had court today. The Court Magistrate was extremely nice, and after explaining the school zone she agreed to amend the charge. She went out of her way to compliment the fact that in 10 years of driving I've had only one other citation, which I thanked her for. To be quite honest, for being in court as a defendant she made it about as pleasant of an experience as it could possibly have been.
I ended up paying a $10 fine + court fee, and 0 points will go on my license.
I can live with that. Losing money is always a bummer, but it could be way worse.
Thanks for all of your helpful replies, folks. Being my first ever time in court I really needed the coaching.
