The best thing to do is hire a lawyer to appear in court for you. Court's do appreciate it when people try to clean up outstanding warrants, but to avoid the risk, hiring a lawyer to make the initial appearance and get all the dates in place means that you are not in court to be arrested. It may cost a little more, but it is worth the expense and peace of mind. It is much better than getting pulled over for some other reason, only to be hauled away for the outstanding warrants.
Good luck to both of you.
