just screw it in the hole on the bridge, the spring/hook is most likely for the section under the back plate. and the "2 L shaped screw driver things" are allen wrenches for the truss rod. Those have nothing to do with the whammy bar, but both are standard accessories. So just look for the hole in the lower right side of the bridge, then take the threaded end of the wammy bar (the shorter end without the white piece) and screw it in all the way then loosen it 3 whole turns. hope that helps.
