Repotting Den. with roots entangled in coconut husk

[Annika]

I have a Den. Burana Princess and Den. Salaya Pink that were potted together in large coconut husks. I don't mean small loose pieces of coconut---these husks are 3-4 inches large. The roots of both plants are completely entangled with the husks. Can anyone suggest how I might go about removing them from the husks so that I can repot them? The husks look pretty deteriorated to me.

Also, the Den. Salaya Pink has a keiki growing on one cane. How and when do I detach and plant it?
Many thanks, everyone! These are my first dendrobiums and I'd like to do well by them.
