OK, you have done a lot of work and spent a lot of money. Did you have this problem before you started?
4.3 litre, model 220 TBI fuel injection. 700R4 tranny.
The most neglected (or not thought of parts) are the TBI parts themselves. Do you get the odd smeel of raw gas?
What I know you need by what you described is a new Fuel pressure regulator.
You buy it already attached to the "fuel meter cover".
It is a simple exchange of parts.
ALWAYS remember to un hook your battery whenever you are working with the fuel system. You have to undo the injector wires, may cause a spark and poof in your face because you will be working very close to it.
This will also give your computor a chance to reset after you exchanged all those other parts.
Let us know what happens.
PS where you getting really crappy gas mileage?
No you don't have to have it scoped and yes it is very simple to do.
You need a # 15 torx screwdriver and locktite for those screws on reassembly.
