Wheels and suspension question

[Mtb154]

I want to lower my forester and change the wheels so what is the best way to lower it? Is impreza suspension a straight swap or can I just buy lowering springs ( like the old days). I was thinking about impreza alloys as well, do I only need to be concerned about getting 5 x 100 fitment wheels? Appreciate any advice given.
