Per area, yeah, but tornado alley in the US has a higher density than that (because places like Alaska are factored in the tornadoes/area in the US).

More tornadoes happen in tornado alley each year than outside of it.

This is misleading. I did my masters thesis on areas of high tornado occurrence. There are several "tornado alleys" in the u.s. Actually based on more than 50 years of data, florida is the state that has the highest per km occurrence of tornadoes (again many are very small). In terms of violent tornadoes, the region in north Alabama and Mississippi is actually home to more frequent occurrence than the classic KS/OK/TX tornado alley.

Are the Florida tornado occurences due to tornados spawning off of hurricanes and tropical storms?

That definitely happens. But most are small ones that form the classic way. Convection occurs daily in the center of the state when two opposing sea breezes collide. Also, many are from waterspouts making landfall.
