Getting ripped off or the necessity?

[Raan]

I am new to getting a snake, and have been doing my research for a little while. I went into a store today that seems very knowledgeable and friendly.He told me if i needed help that he would even help me set the tank up if I brought it in. He was telling me for a ball python, just a baby still very small all I will need is a 10gal tank, also I will need a day time and night time heating lamp, as well as a UTH. I am wondering if all 3 of the heating requirements are true or just something extra and not needed. Please feel free to give you 2 cents.
