That's all the right parts and they go together in just that order. They are nice jacks... The first black piece goes on, like it is, it ought to stretch to fit over the cable. Then the blue thing, the same direction it's pointing, strip the outer coating of the cable about 3/8", strip the two inner wires about 3/16", solder them to the lugs, slide the last silver bit over the tip and spin into the black thing you put on first... Same for the other end... just make sure the same color wires get connected to the same lugs.
