At the load end you should have a black wire going from the black screw up to the light. The black and red of the 14/3 should be connected to the 2 silver terminals at both ends. The whites should be tied together and not connected to the mechanical switches.
Once you get it back in working order, you will need to relay the power or wire going up to the light to the other end (depending on which end you want the switch at). You can use the black wire of the 14/3 to do that. Lutron uses a sledge-hammer approach and has you tie multiple wires together. This is to minimize the effect if you chose the wrong wire.
