NJ does not have high misdemeanors or any misdemeanors for that matter. NJ has disorderly persons offense and crimes. There is a three strike provision 2C:43-7.1 but it applies only to violent offenses. The charges you list seem to be DPs or even town ordinances. 3 strikes does not apply.
There is no way to answer your question other than there is no three strikes law in New Jersey as was previously stated. There are disorderly person offenses, petty disorderly person offenses, and crimes of the first, second, third and fourth degree in New Jersey.
Are you concerned how going to neighborhood mediation would impact PTI? Have you been to mediation before on a noise violation previously? The question is not clear on what you want answered.
