I would not recommend running a stock FPR and fuel pump on 10-12psi.
Also, w/ 120k miles on the clock, I would suggest replacing a few things:

1) Timing belt and tensioner
2) Cap, Rotor, Coil, Wires
3) Oil/Water Pump

Those things are KEY to making an engine last. Some HASPORT mounts would be nice (personal experience) and a valve adjustment would also be very helpful in this stage of the game. good luck...let us know if you have any other questions.
