Here's the deal...I'm in NY too...done this plenty of times.

as others said...plea not-guilty...and wait for a court date.
If you know any police officers, have them call the ticketing officer and put in a good word for you...THIS HELPS.
It may take a few years to even get a court date. When you do go...bring cash with you so you can pay your fine that day (they like this). They will plea-bargain with you before you get called up in front of the judge. OR, you may even get lucky and get it dismissed if the officer doesn't show up (not sure if this happens anymore w/ troopers, I think they changed the rules).
With that kind of speed, you'll probably get stuck with some points (and a nice sized fine)...take a defensive driving class (this will take some points off). One of my tickets, defensive driving was part of the plea-bargain...I had to take it and go back to court w/ proof.:( So if you take it ahead of time and bring proof with you, that might help. Also TRY and keep your record clean between now and your court date, should help also.
From what I can remember about "points"...They are retro-active from the date of the ticket (but don't actually show up until your court date). Some points (2 I think) come off every 18months. So if it takes 2 years to go to court, some of the points have already come off your record before they even show up. (kinda confusing, I know). Your license wont get suspended unless you have over 11 points or get 3 speeding tickets within a year. And your insurance shouldn't go up unless there's a change in your policy and they notice the ticket (they wont get automatically notified that you got a ticket).
