Hi, Should the raised-rib panels have a bead of silicone applied at the overlaps? If not, what is to prevent the damming effect from the protrusions (soil vent, etc) from building up a high level of water during heavy rains and overflowing the rib overlap?

It depends upon the panel and your roof pitch. Check with the roofing manufacturer
