"Be sure the shaft rotates around the sweetspot and not vice-versa."

I've never understood this...at all.

Or when ppl say "Hosel rotates around the sweetspot."

I look at my club and go "HUUUUU-what??"

The line of pull through the sweetspot is a line from the #3 pressure point through the sweetspot. Tape a piece of string on the sweetspot and take it up to the #3 pressure point. That line is the center of gravity, not the shaft. Imagine the toe and the shaft moving around the sweetspot. In fact, once you add the string, do some basic motions and watch the sweetspot. If there's any Turn and Roll, you'll see the shaft moving around. The clubhead doesn't flop around the shaft.
