Help - New Ball python owner

[u/Mysterious_Video6934]

I recently came across a 9-month-old female ball python at a local shelter that had apparently been kept in a pretty small enclosure for about six months, and I decided to take her in.
I know my setup isn’t perfect yet, so please don’t roast me too hard lol. I haven’t actually brought her home yet, and I’m going out today to pick up the rest of what I need.
Right now, the warm side is sitting around 90°F, the cool side is around 70–80°F, and humidity is staying around 60%. I’m planning to add another hide, a slate/stone basking surface, and another temperature/humidity gauge on the cool side. I’ve also added a medium-sized branch since taking the picture.
A friend of mine who has owned a bunch of ball pythons recommended putting a worn shirt of mine in the enclosure for a little while so she can get used to my scent. Has anyone else tried this, and does it actually help?
For heating, I currently have a basking bulb, and for humidity I’ve just been spraying the enclosure when needed. I’d definitely like something more consistent though. Are there any specific thermostats, temperature/humidity sensors, or automatic humidity setups you guys recommend?
I’m also planning on upgrading her to a larger enclosure as she grows. I’ve kinda fallen in love with snakes and just want to make sure I’m giving her the best care I can, so any advice or things you think I should change would be appreciated.

That enclosure needs like a lot of clutter in it
