Help with Car physics

Hello. First off, i am really new to blender. I have made my car (very basic) the wheels dont turn or anything. Basically, its just a block, shaped like a car. I know how to make it drive and that but i have some questions with the physics car. first off

  1. How do i make it so when i drive over a jump the back end of the car “levels out”, what i mean is right now the back end of the car stays the same height as the front end of the car. I know this has to do with the lack of phsics that i have with my car already.
  2. Does anyone know of tutorials on how to make the wheels spin when i go forward and turn when i …well…turn?
  3. I have my track and it is made of 2 different planes. When i drive over lane 2, i fall right through it. Why?

Thanks, any help would be appreciated.
