As far as the professional eligibility:
NCAA Collegeiate rules state you must be an amateur athlete to participate in any sanctioned swim meets. However, local clubs, YMCA, things like that, have a different set of rules, as does FINA. With FINA, and most clubs, you can be pro and still swim (obviously, or the Texas Trio and most of the other Olympic swimmers would be ineligible).....the only rule I ever ran across for YMCA and local clubs is that you cannot swim both high school and club at the same time (that obviously doesn't apply here)......
