What your dad said is very true - but could be pretty much applied to any animal. :lol:
Since you have 'Princia' vanwaerebecki, as J&J said, the husbandry is the same with all hissers. Breeding hissers is effortless. Heating the cage is fine, but they can breed at room temperature, provided that you don't live in a log cabin in Alaska. I can't give suggestions on heat lamps if you're dead set on getting one, because i don't use any. I don't freak out over my humidity levels, but i occasionally pour water into the substrate. I've heard that small nymphs need some humidity to survive, but you should look that up. Most suggest keeping humidity levels up, but you don't need to worry too much if your enclosure is not bone-dry.
The guy i got my hissers from swears by substrate-less enclosures and egg cartons. I use substrate and egg cartons in my closures, but substrate is optional for hissers. They might like it more, but it depends on your preferences (cleaning and maintainability, aesthetics, humidity, etc). Egg cartons are a must based on your enclosure size.You don't want an over-crowded enclosure, but if you're starting out with a few hissers and your enclosure is generally flat and more than a gallon you should be fine without egg cartons.
