Adjustment screws are there to make sure the wheel fits in the frame the right way each time you remove it and replace it. Therefore by definition you don't change the screw adjustment because you want those screws in the same place every time. And your squeaking BRAKES might easily be fixed by running a Scotch Brite pad around the rim braking surface or roughing up the brake pads a little with some sandpaper.
