In addition to the NO DUI, and that you already said you have modified your driving habits. Own the tickets when asked, regardless of how you got them (ie. Stop sign behind store). Stop sign is a stop sign, no excuses. When you are asked, be able to say that you learned and make sure the rest of your driving history prove it.
As a side note to, consider your age and the type car you drive into how you drive. Because no cop ever gave a kid in a hotrod a ticket, just because.
Good luck with your career.
