Take it for what it is worth...
You are spending too much for that animal. What I mean by that is not a high dollar animal. It would be much cheaper to get something like that local to you and not incur the shipping costs.
The "weather" outside of the enclosure can dictate the degree of difficulty in keeping the animal's environment right. For example AC zaps humidity and you should equip accordingly.
I think also you are buying way too much stuff up front. A baby ball needs nothing more than a shoe box size plastic container. Focus on the heating and humidity aspects and you will have a much better start to your experience. Once you have it eating, shedding well and growing, then start thinking what you want your final setup to be. A good thermostat, heat gun and heat tape/pad are the most important things to spend money on.
