Replacing a fuel pressure regulator at a shop usually runs $150 to $500. The regulator itself is cheap; cost varies based on whether it is mounted on the rail or inside the fuel tank with the pump module.
Most drivers pay $200 to $350 at an independent shop. In-tank regulators integrated with the pump can push the high end past $700.
Rail-mounted regulators are quick; in-tank regulators require dropping the fuel tank.
If the regulator is part of the pump assembly, you may have to replace the whole module.
Older vacuum-style regulators are easy. Newer returnless systems use a sensor and pump-driver instead.
Aftermarket Standard, Delphi, and Bosch are reliable. OEM is 40-80% more.
Often replaced together if it is the in-tank style.
Dealerships are typically 50%+ more than independent shops on fuel system work.

Short distances yes, but you risk fouling spark plugs, damaging the catalytic converter, and getting stranded with a no-start.
Often yes - P0171/P0174 (too lean), P0172/P0175 (too rich), or P0087 (low fuel pressure).
Rail-mounted yes - often under an hour. In-tank regulator means dropping the fuel tank and can take 3 hours.
If the filter is in-tank with the regulator, yes. If it is a separate inline filter, replace it if it is past its service interval.
Long term yes - excessive fuel washes oil off cylinder walls and can damage the catalytic converter from unburned fuel.
