Thank you good Sir

Excuse my ignorance as this is my very first Android device (working one that is)
Read quite a bit of articles & tuts Still afraid I'll mess up, so I have a few questions regarding above files & compatibility with my devices in it's current state

Currently at stock 23.4.A.1.264 (Netherlands Customized) updated via OTA from .200
"Bootloader unlock allowed = No", not rooted. Originally was on Croatia (VIP carrier, KitKat)

Am I good to go with such setup?
OR before doing steps above do I need to enable:

Debugging
Disabled apps (some google ones)
Format my SDXC card since I have a lots of things there, If so to which format since it's SDXC card
Backup my device to PC with Sony Software or any other method/tool

Reason I'm this scared is guy who owned it before me flashed it to another countrys ROM. I do not know which tool/method he used and in which way now does this effect doing step 4 If something goes wrong I have no idea how to take further actions.
