well no expert... but I would think this is NOT the trem for considering whether you like it or not... as it has to be screwed to the body... and there is no reversing that w/o refinish. as I understand... the screws for trem mount - go through that washer there and thru the trem into the body. the spring then sits on top of that washer and under the receiver in the trem arm.
afa tom bridge - I believe they (dussen) a tele bridge that mounts on std tele holes.
afa neck, not a big fan of the shim idea... but it will work. if it were me... I'd be much more inclined to glue a piece to the bottom of the neck, use hide glue, use my planer sled to cut it at the proper angle. best of both worlds... can always remove it later with some heat/steam... but will be secured to the neck.
