Goldie, as to the first: CYLOR. Some factors include if you’re going to run out, if not washing will make the items moldy or cause someone to suffer from the smells, if there are kids who have accidents or get sick, etc.
Just keep sorting the laundry every day to make the post 9 days clean up easier (and iy”H may we get to do laundry much sooner!).
As to the second, can’t help you, but curious, are you makpid to eat meat every rosh chodesh? I would guess that if it were allowed, you can be sure everyone would eat, even if they weren’t machshiv r”ch so every month.
