Should I talk to the prosecutor when I take the ticket to the courthouse to let them know that I plan to fight the charge and have the charge dropped before I ask for a trial or wait until after I get a trial date and disclosure.

I just got a ticket on sunday for 146 in 100. The officer wrote the ticket for 140 in 100. I plan to fight the ticket but the officer did not put an offence date on the ticket. Is this an easy win.
