A: Since both contestants will advance (based on this year's rules), the results of a contest don't matter as much as the experience that the speakers gain by participating in the club contest.
I would suggest that you either run a contest or at least adapt the introductions to closely match a contest. You may want to have multiple evaluators instead of multiple judges so that each speaker can get more feedback.
I would also suggest at least a few evaluators to use the judging forms as the basis for their evaluation so that the changes / improvements to the contestants speech will (hopefully) be reflected in their scores at the area contest.
What would you suggest? Leave a comment for other readers to see !
