I have an import Supercharger.

I've located the idle control screw but it's fully turned clockwise.

What can I do to get cold start idle to 800 rpm from the get go?

There is a little bit of a surge in revs as well when you come to a stop and
put the car in neutral.I'm not convinced it was designed to do that.
Any other tips for fuel saving on short trips much appreicated!

Always thought the revs increase as a result of the servo being connected to the inlet, so pumping the brake may pump air into the inlet.

No it's due to the idle-up VSV supplying more air to the inlet, if you think about it the brake servo cannot do that, there is nothing going to atmosphere at the servo end, it's sealed.The ECU has a STP input, so knows when the brake pedal is being pressed and opens the idle-up VSV.

I think the car does the brake controlled idle up control directly via a diode from the brake light wiring?
