1. Correct. That's a problem with the 3V engines.
2. I bought a set of these KD tools:
Permanently attached swivels so they don't come apart. Plus, they're magnetized and hold the plug perfectly so you don't need to use a rubber hose to start the new plug.
3. Stripping coming out isn't a problem, overtightening when installing is.
4. 13ft lbs. for the '03.
5. Dunno what Creep is, but in all honesty, you're less likely to spit a plug on the '03 MY because Ford increased the threads per plug hole in '03.
There were less threads in the '99 - '02 MY engines so the margin for error when replacing the plugs was very slim.
...or after i'm done 20k miles later a plug will blow.
Just check your plugs occasionally and you should be fine.
