that be best way to shut water or do I have to shut the whole house

The purpose of the shut-off valves at the fixture is so that the water
can be shut off at the fixture without turning off the water supply to
the entire house.

The pipe that goes from the wall to the pedestal- shaped like a U, I
remove that from the wall?

Yes. Stuff a rag in the hole in the wall to prevent sewer gases from
entering the room until you are ready reinstall or install a new
fixture.
