If using a propane tank, the tank valve IS the "outside" shutoff valve.
Not necessarily. It depends on the distance between the wall where the penetration occurs and the tank itself. If it is more than 5 feet, a valve is required at the point of penetration.

On commercial installations, a valve at the point of penetration is required, regardless of the distance.

It is good practice, generally speaking, to place a valve at the point of penetration. This allows you to keep the tank a fair distance from the house (or stucture).

This is along the lines of putting flashback arrestors on surface mix torches - not totally required, but not a bad idea either.

Also, NG is permitted up to 10 PSI with a special permit, check with your local NG distributor.
