Re: Two Black and Two White wires for GFCI
More simply, the GFCI terminals should be marked with "Line" and "Load". Your incoming hot wires connect to the "Line" terminals as described by MLB, the second set of wires connect to the "Load" terminals, ground, of course, goes to ground terminal, pigtail the two lines with a short wire to attach to the ground terminal of the GFCI.
