Action

Not applicable. Tumbling is part of movement, so a Tumble check is part of a move action.

Try again

Usually no. An audience, once it has judged a tumbler as an uninteresting performer, is not receptive to repeat performances. You can try to reduce damage from a fall as an instant reaction only once per fall.
