Can you describe better? If round 1/4 in. clay like balls it's probably hygroton or similar. No need to replace, just follow Brian advice on drainage.
2. Fred told me the temperature needs to be between 60-85? He said room temperature is fine as long as I'm misting. Can I just get a spray bottle for the misting? Fred said it would be fine but I want to make sure.
I would follow temperature and humidity recommendations in care article Brian linked. Yes, do get a new spray bottle that has not been used with chemicals!
3. Should I get a temperature and humidity gauge? The man at the conservatory told me it isn't necessary, he said as long as your home is room temperature, the combination of misting and the setup of the tank (sphagnum moss etc) should keep the humidity just fine.
Yes, gauges are needed to help maintain correct parameters. When you go shopping for gauges digital are preferred but costlier. If getting analog, do compare them at store and avoid any that stray from median (average group reading). Depending on room temperature/humidity you might need to make adjustments to spraying schedule or use a heating bulb.
4. Do I NEED to coat the crickets in vitamins? I'm feeding them carrots, which he said should be fine too.
Yes, recommend Repashy or ReptoCal products. Dust crickets with calcium 2 X and multi-vitamins 1 x weekly (on different days and skip a day between dustings). Feed (gut load) crickets 48 hours minimum on carrots and Repashy's Bug Burger.
