so does the number of prongs on a spark plug effect combustion completion?

A 3 prong just allows the spark to have 3 paths so it can take the one with the
least resistance. If the pressure in the cylinder is to great for the gap it wont really matter how many prongs the spark plug has.

Blow out is caused by too much pressure, this happens when very high boost is ran
with too much gap. Thing is that when you increase the gap the voltage is also increased.
I have used both 3 and 1 prong plugs and haven't really found a difference between the 2. Only thing that you might get is a little longer use out of the 3 prong.

2. the dynamics of the chamber and flame speed determine the real combustion properties
maximizing the ignition area has some impact though. Thus a larger gap will cause a larger/longer spark to ignite the mixture.
