Well, I've gone through my first ticket, pretty similar to yours. First step is to either mail in the ticket with a request for trial, and make sure you wish to dispute the evidence. Safer bet if you don't mind the trip, is to go hand it in in person at the court house for where you got it.
Second part is you should get a letter in about 2-4 weeks with your trial date, this likely won't be for a good 6-9 months later. Now you want to make a disclosure request. They have cookie cutter forms in the court house, but there is more things you will want to ask for specifically, so make your own with all the information on theirs, plus a request for additional information, such as what radar the officer used, manual sections related to operation and testing procedures, typed copies of any notes the officer has, and a copy of his records for testing the radar device on that day. The clerk may give you a hard time about handing in your own, but tell them its perfectly legal, and you'll just fax one in if they don't take it. Others suggest just faxing it in regardless, keep a record of the transmission. Also don't include your phone number, just mailing address.
Once you do get your disclosure ( call the office and ask about it if you don't after a month), take a look through it for any glaring errors, they'd have to be fairly blatant errors mind you. Now would be a good time to go for a consultation with a para legal, and they'll give you a good idea if there is any good chance to win. If the para legal thinks its mostly hopeless, your down to two options.
Is the court date more than 13 months from the time of the incident, You can go the 11b route. Otherwise you can show up, see if the officer is there. If he is, go and pay your ticket, or plead guilty to the 10 over. They'll only raise the charge if you want to fight it. If the officer doesn't show, they have no evidence against you, you win.
JP is only interested in if you were speeding or not, reason doesn't matter. Defense must be solid as the officer gets the benefit of the doubt, not you.
