Welcome to the forum Shawnee.

Sounds like you have things planned out pretty well. No need to be nervous.

A few things to add for now; be sure and get a thermostat for your UTH to prevent belly burns, get a combo digital thermometer/hygrometer (Acu-Rite) from Walmart in the hardware section, and get a infrared temp gun at a tool place or Amazon.

Humidy and temp issues can tweaked if and when they arise.

Please post pics of your new snake when he arrives!
