Jail is not an option on a Class 3 Misdemeanor unless you have lots of priors.
I think the max fine is $200 (plus costs).
You will however end up with a criminal conviction.
The question is if you have any defense. We have no way of telling.
Public defenders, by the way, aren't for those who are unwilling to pay for private counsel, only those who are indigent and unable.
To obtain discovery, you write a request to the person with the information (most likely the prosecutor) for what you want.
If they don't respond in seven days, you can go to the court and make a motion to there.
