Probably a good idea. In my opinion, the lower grilles are the place to block. The upper area has the radiator fan behind it, and I see that as an easy, automatic temp control. If your grille blocks become too aggressive but the fan can still draw air, you're less likely to burn your engine up. On my Ranger, the gap between the bottom of the grille and the top of the bumper was huge, and the opening in the bumper was unnecessary. Blocking them off would probably be a great idea.
As for the air intake, I don't know what Ford's thinking, but mine was kind of hidden too, even with the airflow going somewhat towards the box. They must know something I don't, 'cause my truck always got plenty of air... *shrug*
