Sorry I fell asleep and forgot I hadn’t replied.
Terrarium plants you could grow yourself if you chose. Leaf litter is fine , I gather dead leaves out the back garden and lightly bake them in the oven just to kill off anything that might be on them. It also makes them nice and crispy to break up and crumble in smaller enclosures
I wouldn’t know the best way to cut a terracotta pot tbh. I’d end up smashing it into pieces lol.
Online information is ok but caresheets aren’t ideal. Humidity isn’t important , just a water dish and some species require/prefer damper substrate.
We all started with just one or 2. It’s frightening how quickly that can escalate
