G'day Ardvark,
Sometimes over the life of a bike we get all sorts of people to service and adjust it. Some should hang up their spanners and others, well!
I'll try to answer your questions as best as possible.
1. Think of it as the last stage of filtering. No matter how good the filter system is some junk will always get through. Think of it this way, If it was the perfect filter nothing would get through, even petrol.
2. I would leave the return filter in place and clean it every 5/6000km's.
3. Look at how much heat is generated by your motor then think that the petrol tank sits above this. Ever felt the temp. of the tank after a run. You would be far better off heat sheilding the tank as the fuel system on your bike circulates the very rapidly.
4. Fuel pressure should be aprox 40 psi, when the motor is operated at high vac.(backing off at high RPM) the pressure regulator will bleed of more than at lower vac.(constant or open throttle). There will be more fuel returned to the tank under these conditions. The amount returned to the tank will depend on the vac. applied to the regulator at that time.
Fuel pressure should always be checked at any service as it can show up so many problems not normall seen.
Hope this helps
