Hello, and to BP.net...

First of all, do not try to feed or handle your new BP for at least a week. Try to leave it alone as much as possible except for changing water and spot cleaning if necessary. Your snake needs this alone time to adjust to its new surroundings.
As mentioned above, provided 2 snug hides, preferably the same kind. That way your snake won't choose security over proper thermoregulation.

It will also help the snake feel more secure if you cover three sides of the tank with something like construction paper, contact paer or aquarium scenery. This will help the tank seem not so open. Also it will help if you add some fake plants or vines inside to fill in some of the space. You can get these at pet stores, but they are cheaper if you look at dollar stores or craft stores.

I usually use an Under Tank Heater that covers at least 1/3 but not more than 1/2 of the floor space, but if the one you have is providing the proper temps then there should be no reason to change it.

What are you using to measure the temperatures and humidity? And, do you have anything to control the Under Tank Heater?

If you could post a photo of your set-up, it would help. In the meantime here are a couple of links that may help out with setting up your tank and a couple of ways to cover the top to help with humidity.
