>2) Stored energy is just N*C*V^2/2. C is the stage capacitance (don't forget 2 C's per stage). V is the stage voltage. N is the number of stages.. Typically you make the caps big enough so that energy going to the load (i.e. I*V*Tcycle) in 1 cycle (1/60th second) is some suitably small fraction of the stored energy (say, 5 or 10%). Then, if you have a flashover, you're only dumping 10 cycles worth of energy, which probably won't be a disaster and melt the grid, etc.
