One trick I've used before is to apply heat around the plug, then squirt some penetrating oil. This makes it easier for the oil to penetrate the threads. Heat it for a minute or so. Make sure there is no wiring or anything near it. You may have to do this several times. It takes about 20 minutes for penetrating oil to get in there good.

The dealership has a tool that will remove it. 1999 to 2004 trucks with the 5.4 have this problem bad, so ford came up with a tool to remove broken spark plugs. Unfortunately you'll have to pay dealer rates, so try rudpro's advice first.
