Just curious. I don't own one myself. One of the magazines we get at the shop had an article about them and in the article it said to remove the trucks cab to gain acess.
On my f150 V6 it's an easy job if I remove the front wheels and change the plugs through the wheel well.
I read on V8's it's a 5 hour job and you have to remove the fuel rails and if the plugs were in there too long and rusted, they'll strip the threads out of the heads when you pull them.

I checked an F150 site that I frequent occationally. I'm sure this would be discussed there if it was a problem. I couldn't find where anybody posted any questions about changing the plugs on their 2004 or newer Ford pickups.
There is a article there on how to change the spark plugs in your 5.4l. It tells you how to change your plugs without removing the fuel rail, but reccomends it just to increase the working space. As for the rust, not a problem. Just amke sure you use never-seize on the new plugs and don't over torque them.
Here is a picture from the article - gives a good idea of what is needed.
Overall, it sounds like an easy, but time consuming job. I take my 4.6 to the mechanic to get the plugs changed. The $$$ that he charges is worth every penny.
Was that a Grand? With a 3.3? My 92 3.0 ..the back is somewhat easier than the front. You can't see them ..but the "hole" is in the alternator bracket and the other two are real easy once you get the air box out. The fronts, although more accessable, tend to leave you with very little swing room for the ratchet ..and you end up hitting, instead of sharp sheet metal, plastic or other rude stuff(dipstick, fan, etc.).
You want a challenge? Do a 2002 Chevy Astro Van with a V6 (probably the only thing they come with). They just needed to give you 1/2" more room on the driver side. The drivers side is impossible (about 4 hours - this included a wire change). You have to tear the interior apart. The passenger side is better ..but the dipstick interferes with the plug shield and you don't have a thin enough socket (I don't even know if they make one thin enough) so you think that the plug is cross threaded as you take it out. You chase the plug hole and it goes in smooth ..you look at the new plug ..it looks fine ...then you figure out that it can't work right and get a rubber hose to put the plug in and thank GOD that it's a tapered thread peanut plug so you don't have to torque it too much with the socket at the odd angle that they setup makes you use.
