1. Sounds like the pump is turning off sooner than before, which results in your pressure being not as high. That is a function of the switch.
2. Sounds like the pump has trouble. Could certainly happen from a lightning storm.
I'd check out the switch first. With the power off and the cover off the switch, try turning the large, center nut a full turn clockwise. Try your system again and see at what pressure the pump cuts off. Keep trying it until you get it where you want it. Many people go with the pump cutting on at 30#and off at 50#. But I'm going to guess that the switch is bad from the lightning as well. Still, won't hurt to try.
