Dashe, I think we're soulmates! I have to write everything according to AP style as well. I will never put a comma before 'and' in a list, and I refuse to accept that 'canceled' can have two Ls.
Web site is always two words, Internet is always capitalized and I never use zip code abbreviations for states anymore (California is Calif., not Ca, Arizona is Ariz., not Az, and Delaware is Del., not De).
My biggest pet peevs, though, stem from grammar, not AP style. It drives me nuts when people use 'good' instead of 'well,' and as strange as it sounds, 'nauseous' instead of 'nauseated' (It's almost always supposed to be the latter, as in "I feel nauseated").
