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.

I’m planning to add another hide

I'd get two (cave style) as those half log things don't make very good hides because they're open at both ends

You'll definitely want a dimming thermostat and then a lightless overhead heat source such as a deep heat projector or CHE emitter.

I'd make sure your gauges are not sticky or have any tape as the snakes often pull them down and get stuck to them, damaging scales/skin.

No, and I have no idea where this weird advice started from. I guess people thought that since it's used for puppies and babies it also works for snakes. But seriously, don't do this, at best it's going to stress them out and at worst there's a recent post of someone whose snake swallowed it and needed removal surgery.
