Jeff Gordon was not stripped of his win, just a points reduction, so according to WFR rules, those who had Gordon still receive 200 points for the win. Everything is time stamped and no picks will be accepted after the starting time of the race. The solution is to make your picks far in advance. You can always change them before the race. All ties between like positions in the final standings and weekly high score will combine and split the prize equally.
Prize winners are responsible for all taxes to be paid on winnings.
