Take your time and take it one step at a time. No rush.
You'll get a million different answers on how to do one simple thing. Watch YouTube videos and Shorts (there a100s of them) and decide what method works best for YOU and what makes you feel most confident in doing.
Avoid Stewmac - they are a major rip-off. You'll find much more affordable tools if you take the time and do some research. Some tools are worth the money though like fret crowning files.
The important thing is you have to take that first step and start the process and not worry about making mistakes. They will happen. We all make them. You can always go back and start again or put it aside for a while until you learn and feel ready to continue.
It's really not that hard. My first re-fret was with my 1980 Les Paul standard. It has neck binding and everything. I made a few rookie mistakes, of course, but in the end, it turned out great and I was excited to do it again in the future.
Good luck!
