Ah yes, another newby.
The collective wisdom and experience of many of use here says that the throttle body still gets dirty and still benefits from cleaning. The teflon coating makes it easier to clean though.
All of the Ford dealerships I have worked at clean throttle bodies. For that matter, Volvo and Chrysler too.
Yes, you should be gentle when cleaning them. I like to use a soft toothbrush and a throttle body cleaner that states that it is safe for teflon throttle bodies.
Ford went to the teflon coating so that they could cut warranty costs. When they made the change they also announced that they would not pay warranty claims for cleaning throttle bodies on the teflon equipped cars. The teflon coating did cut down on the need to clean, but really what it did is make it so that it would "get by" until it was out of warranty. When a Ford technician has a problem with a dirty throttle body with a car under warranty, he must either clean it without getting paid for it (and not documenting that he cleaned it as well) or replace it. If they replace too many, they get flagged in the warranty system for warranty abuse.
Truly though, the teflon does help, but it doesn't eliminate the need.

If you are "lucky" (or unlucky depending on how you look at it), after the warranty is over, they will suggest to clean it for $127.

Note that Ford decision makers did not teflon coat the EGR passages that build up and cause the throttle body and valve to become dirty! So misguided rationale on their part is my opinion.
