Info up the top, and dividends are paid out everyday until you un-delegate the SP i think..

You will have to use steem to power them up with SP.... Not just give them SP

I'm not 100% sure on any of this as i have never done it..
In no way do i have anything to do with the guy that runs @voteme i just seen all you guys hadn't had any response yet so i have tried to help :)
