Now here's a question I have always wondered: when the Shuttle is shuttled across the country on the back of the Shuttle Carrier Aircraft do they land together or do they separate and land individually?

They land together. On the east side of the Shuttle Landing Facility the Mate/Demate Device separates the orbiter from the 747.

You can see pictures of the SCA/orbiter stack landing in Florida from Atlantis' return after STS-117 in this recent thread: STS-117: Atlantis Heads Back to Florida

Thanks for your responses the minute I saw the image I realized I had seen it before but it brings me another ( Dumb ) question. I have read that the Shuttle flies like a house brick but are the shuttles flight surfaces used during the landing or are they set neutral.

The "flies like a brick" statement refers to it's rapid rate of descent...much more rapid than most aircraft or gliders. However, the aerodynamic surfaces do work and are employed, as the commander lands under manual control.

The flight surfaces are used just like a normal airplane when landing - but landing much faster and comes down a lot steeper.

If they weren't used, then yes, it would land with the gracefulness of a falling brick....and couldn't be used again.

In case it is what you were thinking, the flight surfaces are only used during landing, and not during launch.

Do you mean landings while attached to the 747-SCA? In this case, I believe the aero surfaces of the orbiter are locked and control is the sole responsibility of the 747-SCA.
