setting up a tank

[Hill1234]

I plan on getting a ball but I wanted to get the terrarium situated first. I have a 10-gallon tank (I was told 10 gallon tank will work until the snake reaches about 28”, is that ok?). I have a small heat lamp, a under tank small heat pad, a hiding place (half log) and a water bowl. I was wondering how should everything be positioned in the tank in order to make everything as comfortable as possible for the snake. Should the heat pad only be used when the heat lamp is not running? I have a digital thermometer and humidity gauge that has two sensors, each one about an inch from the substrate on both ends of the tank. I have read several read suggested temperature variations from like 70 to 95 F but everything I am reading seems to vary so what would you all recommend?
