There might be a specification for that in the FSM but I don't know where it would be. I think the throttle plate stop (screw) should be adjusted so the throttle plate is closed as much as possible without the plate sticking in the bore of the throttle body.
The IAC has a passageway the routes air behind the throttle plate to supply the air needed at idle. That is what should be controlling the idle speed, not the throttle plate.
Sometimes when people are trying to sell their Reatta they post photos of it while it's wet to make the paint look shinier. I can't tell much difference in my Reatta between wet and dry in the photos I took this morning after washing and drying it. I think mine looks shinier dry.
