Yes, I changed mine about a month or two ago. It's no big deal, very straightforward. You have the new plugs so you will not have to worry about breaking any of them. Motorcraft part# SP509

Yeah you are good dude...I believe the cutoff was like November of 07' for the crappy 2-piece plugs.
EDIT: Yeah, sticky on top says November 9, 2007 and before had the plug issue.
