I agree with M5L5 I think you have most everything. I don't have the smog pump on my car but I have the EGR. I remove all the vacuum related stuff for the smog ran a new line from the manifold to the EGR regulator solenoid and a line out of the solenoid to the EGR valve. It's very clean when done that way.
I my experience the EGR valve will hit an aftermarket adjustable fuel pressure regulator like you have, and that's probably way you don't have one. I'm not sure the point of the adjustable FPR in most builds as it is really just a band aid to try and fix a bad setup. I would go back to a stock regulator.
