Welcome to the Site!
Very pretty snake you just got there, I hope we'll be able to help you out in getting everything set up.
First question is what are you using to measure your temps. A digital thermometer? Or one of the radial ones that attach directly to the glass?
Are you using a thermostat to control the power output coming from your lamp and UTH?
Are you using a glass tank or a plastic tub?
Your warm side temperatures are too low providing that your measurements are accurate, you'll want to get them up to the 90-92 degree range. Theres a few ways you can accomplish this depending on the type of enclosure you are using.
