As for the less and fewer conundrum, it's pretty simple: "Fewer" is for things you can count, and "less" is for things you can't.
The Atlantic has LESS water than the Pacific. Bob vowed to eat FEWER hamburgers.
A peeve of mine is using "that" instead of "who" when referring to people. "Wabigoon hates those WHO fart in church." "That" is for objects and such. "The dog THAT barked."
