Switching from glass to tubs?

I'm planning to get my herps moved to tubs before it gets too cold, and I have a few questions. I need to move 2 adult Leo's (they'll be housed separately), a hatchling BP (150-200 grams), and an adult male. I was thinking 16 qts for the hatchling and 28 for the male. Is this okay? Also, what should the Leo's be housed in?
Can I just remove the heat pads and thermostats from the glass enclosures and put them on the tubs?
Sorry for all the questions- I want to make sure I've got everything right!
Thanks!!

Not sure about the lizards, but I saw it was recommended for an adult BP to be in a 32qt tub (male anyway). I guess that's not very helpful for your lizards or the baby, but I do know there's a VERY excellent guide on how to set up a tub enclosure by Vypyrz in this same subforum, it's the first sticky I think.

It shows a really great way to put the UTH under the tubs for easy access, if you haven't already seen that, definitely check it out!!
