I only do one thing after every ride. I put my chain in the small ring in front and small ring in back. I like to take as much pressure off of the cables and springs as possible. This was just something my brother told me to do a long time ago, have no idea if it helps or not but it doesn't hurt anything.
Oh, if you have rapid rise then you would need to be in the small front, big rear to take the tension off.
