i = dQ/dt, but I can't figure out how to derive/integrate here :(

No integration is required. You're given the current (0.5 A) and the time that it flows for each pulse (0.10 μs). If 0.5 A flows for 0.10 μs, how much charge has moved?

For part b), do we just divide average current per pulse by number of pulses per second?

The average current will be given by the total charges moved in a second, divided by one second. You've found the charge q moved per pulse, and you know the number of pulses per second, so...

What are the units of power? What's the energy per charge? Per pulse?
