Obviously, as you are only 2 years into college, you won't be applying for another year or two which is time for this process to work itself out.
Underage drinking and then driving, is, by definition, something done by a person who is not fully mature. Putting some time between you and the incident is wise. You admit that you were wrong to drink when underage and that you did not think through the consequences of driving after drinking, in part because drinking impairs one's mind.
Stealing branded clothing from the coach's area of a stadium.... was this a prank or a dare, or did you think you could get away with it? Did you intend to sell the stuff or use it? (you need not answer here, but these are questions that should be answered if you do need to write this up as an IA/misdemeanor) I hope, for your sake, that the charges are dropped. If not you'll need to explain in detail what was taken, and why you did so. Show remorse and, obviously, note that you would never do such a thing ever again.
