I'd do one, and pull the IP off the head so you have some room.

2 teeth if you were going crazy, and its not geared at towing so much.

Depends on the pop pressure. If they are the standard 1st gen pop pressure (and I think jkidds are) then I'd leave it alone and just bump the pump to taste.
RIP 91.5 W250 5 speed. The great experiment.
