Cyclones (hurricanes) are not caused by the Coriolis effect, but by low pressure gradients. An increased Coriolis effect might make cyclones form faster, but if the other components needed to make hurricanes (warm water and a pressure change, basically) are not there, no amount of spinning will make them form. Basically hurricanes form over warm water, so if your planet contains more warm water than Earth, then it will have more hurricanes.

And I think your ideas for extra horse bands/doldums are pretty good. I don't know exactly what would happen with all that, so making more bands seems like a pretty good idea. You seem to know your stuff! I hate it when people just draw random climates in random places with no knowledge of how climatology or plate tectonics work.
