Where to insulate?

Any opinions would be appreciated on: (1) how much good the insulation actually does, and (2) if it causes problems with the carpet.

1) Do not insulate the inside of the trunk; 2) Do not insulate the inside of the car; 3) Insulate the front and sides of the foot wells, as seen in the pic of my car below -- this is really the only place you really need to insulate; 4) The underside of the tunnel is purely optional -- I don't think it makes a difference, I don't have mine insulated, and it doesn't get hot on the inside of the tunnel. I've been under there when everything else on the car was red hot, and that area was still not hot.
