What you should do will depend on several different factors. One factor is your driving record. If you have a good record, then the Court will most likely be lenient with you. You can appear in court to ask for leniency and perhaps the prosecutor will allow you to plead guilty to the lesser of the two charges in exchange for a dismissal of the other charge. Since you have already paid the outstanding ticket, the Court may just dismiss the driving while suspended charge.
It is highly recommended that you seek the assistance of an attorney in your area as the attorney may be able to get even better deals.
