you are like the guy who never goes to the doctor then one day shows up with a list of questions....and oh BTW, i'm having chest pain, doc! :evil:
sounds like you are headed in the right direction. 14 to 21ish days on the queen, then mating, etc. probably closer to 14, but i have had two go longer this year and i think it was weather.
bees with no queen and little brood to protect will spend their time packing in honey and pollen. this is good for you, but can clog up your hive quickly. keep a close eye on it.
why do you have an excluder on? you have no queen :-D. this is your chance to let them work the honey super without interference. let them get a good start on it and then later, if you feel you must, add the excluder. if you put excluders between brood and honey supers, especially new honey supers, you get no action above most of the time..... if you let them get a started working the honey supers, they will continue when you put the excluder on later.
if your new queen gets up there before you put the thing on, a little brood in your honey will not kill you!
