Welcome!

1. What is the official minimalized workflow to become a Blender developer?

https://wiki.blender.org/wiki/Developer_Intro/Overview

2. What/Where is the repository and is it able to be synced locally to TortoiseSVN?

We use Git, see: Using Git - Blender Developer Documentation

3. Is the workflow similar to building branches, changing code, creating tasks, pushing to branches, then doing pull requests to be merged later? If so, where is the said tracker and branch manager?

5. What is the workflow to get features merged into master? Who approves this? Is it more vote based? Are there any key heads calling the shots?

It’s a bit different than GitHub, see:

Yes, just use the toolbar above the textfield.
