Welcome to the FordForum.
Be sure to check the NCPOC forums as well. Anyone with a slim connection to the state of North Carolina is welcome.
The fuel filter is somewhere under the hood I'm told. Perhaps it is obvious I've not changed mine? It's on the list of things to do.
There are two crankshaft position sensors. One (CKP1) is in the distributor, the second(CKP2) is located at the crankshaft pulley opposite the timing indicator bracket, about 4 to 5 O'clock. It looks pretty easy to get to from the manual, but I couldn't see it, so I just don't know.
You shouldn't have any problem changing them, the car is o.k. to work on, it's just tight.
There are alot of good sites with information on malfunction codes etc. If you need them, ask.
