as far as keeping them separate, I actually keep hatchling from the same clutch together. I don't see a reason to separate them outside of that.

By the way, thats an awesome set up you have constructed there. I've not seen a fully function one a long those lines before. Great job! especially with the pothos doing so well.

P.s. might want to check out the forums at geckounlimited as well. there are a ton of uroplatus keepers that might have some info for you too. between the two forums, a good amount of info is available.
