- I am using both a 50w red bulb and a UTH. How could I increase the ambient temp without making the warm side too hot? ( The UTH plus the red bulb, make the warm side hot very quickly)
Raise the temp in the room

- Both of those are running into the same thermostat.
Good deal

- To measure temps I use a digital thermo w/ probe to measure the heat inside the hide on the warm side. I have another digital thermo/hydro measuring ambient and humidity located on the cool side.
Perfect

- I am using two Exo Terra rock caves as hides. The medium size ones, they can be found their site.
These still might be to big for her and as such some what relating to her not eating

- She never leaves her hide on the warm side, or at least I never see her leave it. When I said she usually curls up in the back corner I meant back corner of the hide.
AAAA.. Ok I see what your saying.. Again smaller is better when it comes to hides my snakes take up the whole hide from the 3000+ gram ones to the 150-200 gram ones they love to cram themselves in to tight really tight places.

- I really do not want to change to a tub because A) I have zero money right now bc of xmas shopping and B) Aesthetically speaking, I doesn't appeal to me.(Sorry?)
Not a problem balls can be house in a great tank setup for their whole lives with no problem once you get them set up right.

- I know she is not refusing food because of an upcoming shed because she shed last week.
Ok so that rules that out

What I find odd is that I had her at school for a week. She was in the 10gal with newspaper for substrate, a Trisket box for hiding, a water dish, and I only had a UTH with no thermostat or anything. She ate fine that week. Now I bring her home, set her up with all this nice stuff ( following the standards set by the caresheet) and now she won't eat! Its so strange.
All of the things your describing are stress factors for your snake. starting in an improper setup, being moved, then being set up in a new home..All that is very stress full for a little snake.

Im not a child, I dont go picking her up out of the cage every hour, and I don't blast music or do things that would frighten her.
No your not a child..your new to ball pythons and as such we have no clue what your handling practices are. It is great that you care enough to have some fore thought into what might scare your new pet.. A+ for that

Could it just be the change in the weather, its been cold, rainy/snowy/icy the past 2 weeks...
Typically not more often than not animals that go off feed due to cooling weather are of breeding age and mature snakes. Babies will go off feed because of illness or stress.

I just don't want to throw in the towel
No reason to there are still many Many tricks that can be done to try and spur your baby to eat..We'll get there
