Welcome to the forums! These sound like fairly common problems, but before I can say for sure I have a few questions...
1. How old is your new corn?
2. If it's an adult, do you know if it was handled much prior to your getting it?
3. How large is the viv? (10 gallon, 20 gallon?)
4. What are the temperatures for the hot and cool sid of the viv, and what do you use for heating? (If you have an Under the Tank Heater [UTH] be sure to get the temp on the glass floor.)
5. How many hides and decorations do you have in the viv?
6. What substrate are you using?
7. What is the humidity in the viv?
8. How often do you hold your snake?
If your hatchling is young, every one of your issues with her could be explained by it, but any of these factors could also play a role in your snake's behavior.
