Welcome Chris,
a) The pins are still the same.
b) The 5v connections from the OSPi board provide power in to the Pi and should not be used if a separate power source is provided. One of the ground (earth) lines should still be connected in order to make a complete circuit for the other pins.
I have been using a flirc case with Pi 4 with very good results. The case is aluminum and is designed to act as a heat sink so that no fan is required therefor it is silent and uses slightly less power.
