You can get them at parts america, about 70 bucks for the ignition and 46 for the doors. If, and thats a big if, you could find a newer pickup in the boneyard, and it has keys, 99-03 door cylinders should work in your truck. If I'm not mistaken your pickup uses a transponder in the key for the ignition. The Ford dealer should be able to reprogram it so the old keys and remote will no longer work.
