My question involves criminal law for the state of: MI

Back in June I was charged with misdemeanor assault and battery (the regular kind, not aggravated) for shoving some literature in the face of a protester. The protester was displaying huge sandwich boards with racist images, and was part of a larger politically motivated group known for doing same. Police were called and came, I was frisked, and not officially arrested but put in the cop car's backseat for safe keeping. He took both of our stories.

I hired an expensive lawyer after the prosecutor decided to take the case, and when lawyer forwarded me the police report it had several errors. Besides inaccurately saying I fled the scene, it said I "punched" the guy when in fact my bare hand never touched his face. I shoved racist literature in his face and jostled his glasses. Anyhow, there have been a couple of pre-trials now, and a trial date has been set. The options now are 1) plea to a charge of disorderly conduct with the hope that it would look better than assault to future employers, or 2) go to trial. It also came out at this time that the protester has been involved in many assault cases where he's been the victim.

My questions are: 1) can the inaccuracy of the police report be addressed during trial, or is the report taken to be an undoubtedly honest explanation of the events? 2) can it be brought up during trial that the guy has been the victim in many similar cases? 3) how likely am I to wind up in the clink? I have no criminal record.
