Definitely go to court, but I would not recommend pleading not guilty - the judge is not going to look favorably upon you for that. Essentially the judge will turn around and ask you if your front plate was missing, if your windows were tinted, etc. Whether or not you were given a chance to fix the items is irrelevant to determining "guilt" in this case. My recommendation would be to go to court plead guilty and ask to have the items changed to correctable offenses. The judge will be much more accomodating if he/she believes you are willing to take responsibility for your actions and are just looking for a reduced judgement.
