I would do a tailwheel course first, then an aerobatic course. (thats if you can find a good instructor to teach either), before doing an IMC or night rating. Unless you have access to a multi aircraft don't bother with that.
Many pilots never really learn to master the aircraft, when you can it makes IMC and indeed night flying a lot easier.
Too many "club" pilots like to tell others about how many bits of paper they have and their flying is sh.t.
