My question involves a speeding ticket from the State of: Minnesota

This is my first speeding ticket so I have no idea what I am doing...
I was passing a vehicle when I got this speeding ticket, so I would like to plea not guilty.
My citation includes a court date but does not specify which court to go to (I figured it out). So I called and they told me I could plea not guilty over the phone and then they would send me info for a new court date. What I am wondering is if I wanna show up to the first court date on the ticket and hope the police officer doesn't show up in which the case may be dropped???? (the court house is a two hour drive each way) Also is it best to drag it out as long as possible?
The other question I have is about filing for a motion of discovery. The courthouse said I cannot do that now because they do not have my information yet, but I am worried I may run out of time (i read somewhere that you have 10 days). AGGGHHHHH!!!!
Any information is much appreciated!
Thanks!
