I only know they later part because we had a feral druid decide to start healing to try and top up the raid and it caused two of the healers to get unchained.
On normal mode people will want to ideally reset their stacks atleast every other tomb. I also always found using two different drop points for the tombs to be the easiest. Everyone in your raid just has to avoid the drop zones when people need to get tombed.
