Reddit reviews World of Warcraft Programming: A Guide and Reference for Creating WoW Addons

It definitely has a steep learning curve and documentation can be difficult to follow, or find, at times. There's a book available that provides full documentation

I've personally come a long way from when I started developing WoW addons, but I did start from where you're starting now. It's been a journey of using the websites you've listed and a lot of googling.

Feel free to message me with any questions and I'll try my best to help out where possible. Alternatively, I commonly use the developer discussion forums on wowinterface.com to seek a lot of assistance.

Lastly, what software are you using to code with?

lua is the programming language.

if you have addons installed, you have the source code.

the blizzard API is how you access the system.

There's a book out there on the topic too, although it's a few years old.
