No president actively took any part in any organized crime activity. Nixon was involved in trying to cover up the Watergate burglary, which was a crime, but it was not very organized and Nixon probably did not know about it until some time after it happened. Truman was backed by the Kansas City mob, but he had no more ties with it than any Kansas City business man had to have in order to stay in business there. Kennedy supporters, including, no doubt his father, were not above accepting help from organized crime, in order to win elections.

Planning a Crime and Committing the crime
This is an opionion question and is not allowed on WikiAnswers, but I will answer it in my opinion. A gang is a formed group. Forming a group is an organized act. Also any crime which is done in concert (that is, with the assistance of another or more persons) is also an organized crime. So if you commit a crime on behalf of a gang, it is an organized crime.
Yes. Both New Orleans and Florida have notorious organized crime families.
