replaced ceiling light wont turn off
My guess is that your outlets were wired as split outlets; the top receptacle was switched with the wall switch, and the bottom was always hot. By default, outlets have the top and bottom receptacles connected together, so when you hooked them up, you made the upper outlet (and the light) always on.

The fix is simple; remove the outlet, and on the hot (black) side, you will find a bit of metal that connects the upper screw to the lower screw. Break that off with some pliers, and things will be okay. You will need to do this on all of the outlets that are wired this way.
