Honestly.. Motorcraft Plugs, use nothing else.
Ford's run best on motorcraft plugs.
Stay away from bosch, they tend to misfire more often than not.
since you didn't say which engine you have, use the recommended OE plug (i.e. dual platnum, finewire iridiium, etc..) don't try and save a few bucks and get a copper plug if it doesn't call for it. some of the engine have a waste spark system where the plug fire tail to tip.. a copper plug will wear out very quickly and will give poor performance from the start.
as for Wires, I run MSD 9.5mm just because.
But running the Motorcraft wires would be excellent, or Prestolite (which makes the motorcraft wires)
Any name brand wire would be ok.. but I'd stay clear of the big box brands, (autozone, o'reillly's, etc..). LIfetime warranties mean nothing if you have to keep swapping wires.
I'm not an fan of OE parts, I prefer aftermarket as often as possible, however Ford's run very very well on OE parts, mainly plugs & sensors.
