First off, welcome to BP.net!
OK, You seem to have lots of moving parts going on here.
First, the white eyes. Kinda' sounds like she might be going into shed, but a picture would help us determine that. Not all of them get crabby when they go into shed. Every snake has it's own personality.
Couple things about your set up. You mention a daytime temp and a night time temp. There's no need for all that. You should shoot for a constant warm side temp of around 90 degrees and a constant cool side temp of around 80 degrees. If you can provide this type of constant temp gradient, she will thermo regulate as needed, day or night.
It also sounds like you only have one hide in the tank. For optimal results you need two identical hides, one on the warm side and one the cool side. Right now you are making her choose between thermo comfort and security...kinda' sounds like she might not have either with all that roaming around.
If your UTH isn't on a thermostat, you need to shut it down until you can get it on one. Those UTHs can get hot enough to burn your snake badly. Kudos for using a laser temp gun, but remember you are measuring spot temps on top of the substrate. Your snake can borrow under the substrate and make contact with the glass directly over the UTH where it can reach 130 degrees if not regulated with a thermostat.
There are several things you can do to get your humidity up. Do a search on "humid hide", and see how to make one that will come in handy during shed time. Also you can cover 3/4 of the top of the tank with plastic wrap or tinfoil. That will help keep some of the humidity in.
Lastly, consider going to a tub set up for your BP. They are inexpensive and make keeping heat and humidity a breeze.
