These are things that I would put down on your applications once you become a commercial pilot and I'm sure you'll have a chance to explain them during your interview, but neither of these things will keep you from becoming a pilot. Everyone makes mistakes. Some people more than others. DUIs are definitely bad, but it doesn't sound like you got anything from the motorcycle accident. Nothing on your driving record from it. The regionals ate desperate already and there are guys flying with DUIs in their background. If it is truly something you want to do, go after it and don't look back. Just try to keep your record as clean as possible from here forward.
