Don't worry too much about this. I had one and failed to pay fines, failed to complete ordered AA, etc.....While it screwed up getting my license for many years I was still able to get a very good job. I am a professional engineer and it has not affected my career. You should not be given jail time for non-payment of fines but you will most likely get some probation, community service, etc....just be honest with the judge and things will work out. As far as teaching, DUI's do not affect your chances at becoming a teacher.....other than finding a way to work if you have no license. Keep your head up and good luck!
