I think they might have started after their writers boot camp and "stick that on the chalkboard" thing. That was ....last week, or two weeks ago. I think they are probably first/second episode as well, but they also have to try to make sure they gel together. At least, I hope so!

Casting will need to be sufficently early, but this is weeks in advance and there's no need to advertise or tell the presses about something so far in advance. It could be that the first episode doesn't have any special guests beside those we saw in the finale.

I agree, not until really close the filming. This is more like a 4B casting timing as we have the same from the finale of the last arc. But they could surprise us!
