Usually, a District Justice goes easy on a first offender. You should probably hire a lawyer to go to the Hearing with her. At the hearing, you or the lawyer may be able to "plea bargain" with the arresting officer to reduce the nature of the offense so it need not be reported on applications.
In my opinion, you should never plead guilty unless you have consulted a lawyer first. If a court hearing is scheduled, she should first plead guilty on any citation, and see if you can get the charges reduced at the hearing.
