I am new to the snake world....Be Gentle

[Ranger13]

I work at a pet store. I am a dog trainer. And lover of all animals. I noticed 2 baby ball phythons hadnt eaten and had lost 10 % of their body wght. So I took them to the vet. One is now on antibiotic injections.I am adopting her! Am totally in love and have a 40 gallon and lights and everything I need to house her(mostly donated)
I am super worried that I am gonna do wrong by her in trying to help.
I have read so much and talked to so many people I am mindblown! lol
She is not here yet as I gave her an injection today and thought itbest to leave her due to stress. My tank is staying at 80 degrees with no heater or lights. The basking light makes it about 92 in the basking area. Is that okay?
Only have newspaper as substrate right now, is that ok? looks uncomfortable? lol
You can see that I am serious, I hope. Any help or encouragement would help
Thanks
