If I want to edit the header file, do I edit the core header.inc file or can I add another file. So when I update, it does not over-write what changes I have made?
Do I need to edit core files or can I add template or theme files?

All modifications to core files and core plugin files will always be overwritten on upgrades. You are always on your own when modifying the codebase as you are deviating from core. You are responsible for maintaining the modifications and reapplying them after upgrades. You will proceed at your own risk. Good luck!
Cheers.
