You don't need to avoid completing anything. You can repeat any quest from the login menu. You just play the game normally. Then the next time you play you either pick up from where you left off, or you click Choose Quest and pick a quest you've already completed and then replay that quest, sort of like you might choose to replay End Time or Well of Eternity for the 100th time. Blizzard mostly wants people to focus on playing full sections of the game "normally" rather than just playing one five-minute stretch of the game over and over again but you can do that too by starting a game at a certain quest, running somewhere, killing stuff, logging out, and then starting a new game at the same quest.

My Amazon CE order says "shipping soon" now, still on track for delivery tomorrow.

Same here, except of course I ordered on October 21. :-P

"Probably" midnight Pacific time but they'll tell us more "soon."

Obviously #3, though ideally I'd be marrying a guy who would be excited enough about D3's launch that he'd wonder how exactly to awkwardly ask if we could postpone the wedding so we could level faster.

The only one of those I can even remotely agree with is the hitboxes, at least for AOE spells. All of those other things seem like great reasons why Diablo III is awesome.
