What pressure am I supposed to be running? and how exactly should the pressure respond to throttle and pinching of return line.

The only info I ahve found is 90 psi unregulated, and roughly 51 regulated. Also, the it should remain relatively steady with throttle?

Yes - it should remain pretty steady. Do you have a Bentley? It has a complete section dedicated to troubleshooting the fuel system. I spent the better part of an afternoon doing each test. It's well worth the investment.
