Re: any ideas re: what to do after swarming (and I see an open queen cup)?
See any eggs? Not knowing if and when a queen hatched, you really cant say when you should expect her to lay. If she hatched the day the swarm left, you should expect to see eggs by now, if she hatched 14-16 days after the swarm, should hopefully find eggs in a week or so.
Before spending the coin on a new queen, I'd either find the virgin/queen, or easier yet, take a frame of new eggs from another hive, shake off all the bees and give it to the swarmed hive, you will know in a day or two if they make queen cells. Then you can decide if you want to order a queen or let them go ahead and raise one.
