If your seat is too high your pelvis would rock up and down and that would limit your cadence. I guess that I am a natural. I've been able to hit 145-150 RPM range since I was 17 and can still do it at 43.
I agree. To find out how you (me included) suck at spinning, hook up to the trainer, do a warm up then unclip on foot. Pedal with one leg, then the other. I started at small intervals, first one minute for five or six sets with each foot, then two minutes, then... well you can figure that out. The one legged interval, a cure for the masher.
