Seattle Problems

Hey everyone!
I have a few problems with Seattle airport, firstly fsx atc seems not to use 34L/16R as much as it should (default scenery). Also, does anyone know any scenery for Seattle I can't seem to find any, and if I do, will it mess up WOAI and will atc use all the runways?
Any help would be greatly appreciated. Sorry if this is in the wrong place.
