Yes, and Yes.
I know Explorer Express's scoops can be ordered pre-painted. I don't know about others.
And Keystone/Good Hoods makes a shaker hood for the Sport Trac. The catch is, that the scoop itself comes in black, and it has to be adapted to mount and make it functional, as it was designed to be installed on the 2001 Job 1 engine, which had a differant intake manifold design. There is a project on this site on how to mount that scoop on a Job 2 and up 4.0L SOHC engine.
