All of that going on all at the same time is not likely at all. Are you sure the engine is actually overheating or is that just what your instrument panel is telling you?
With all of those things going on at the same time, here is what I would do. First I would take a REAL HARD look at the charging system. Goofy stuff like this is often caused by a battery with a shorted cell or an alternator with bad diodes that is feeding AC current into the computer network. The computers tend to do really goofy things when they are suffering from malnutrition.
Once I am satisfied that the charging system is in good condition, then I would clear the codes and go on a road test. If the check engine light comes back on, I would immediately scan the engine controller to find out which of the codes came back and fix it FIRST. Many times, fixing one code can fix ALL the codes. By doing it this way, you are more likely to find which one is your MAIN problem.
If your engine is actually overheating, all I can say is you need to diagnose your engine cooling system to find out why...all of the misfire codes could very likely be a result of the engine overheating and fixing the engine cooling system will most likely fix these codes.

All these are fuel trim codes and fuel control O2 sensor related codes, you have something that is causing this as all the sensors seldom fail. My advice here is to see a Ford dealer for the diagnostics before any parts are replaced.
