"In the switch box, I have three separate wires; 1) the hot wire for the ceiling switch, 2) a traveler wire going from the second switch to the porch light, and 3) a traveler to the receptacle."
A Traveler will only be used between 3 and/or 4 way switches and always a pair of them.
And you never have a single wire going anyplace. It is either a cable or conduit that has 3 or more wires.
So I have no idea of what you have.
I think that it would be best to get an electrican to finish it.
