Theres a difference between the voltage in tha spark, and the energy in the
spark. A high voltage will make a long spark, but it is the energy in the
spark (or in your case, the coil) that will make the spark last.
AFAIK, once the spark is initiated, it basicly boils down to an ohmic
restanance where you just wait for the energy to be discharged into it.

If You use an automotive ignition-coild and pulse the current on the
primary, I'd say is is DC. you shut off the current, and the coild makes a
flyback-voltage, which is in one direction only. For it to be AC would
require some kind of capacitor it could swing/oscillate with (sp?)
> B) Why doesn't my voltage increase when I put two coils in parallel?
Because voltage comes from the magnetic fiels collapsing in the coils. You
basicly have two batteries in parallel, which doesnt increase voltage.
However, it does increase spark energy which should make the sparks last
