What you’re proposing almost sounds like a 3rd version of the documentation: “Comprehensive Guide for Beginners”
The Getting Started guide that I had envisioned would be much simpler and would serve to get new users up & running in 30-60 mins (depending on virt platform). I think your “End goal” captures all the requirements:
To that end, I would cut #6,7,9,11,12. Instead provide links to the main docs. Whonix has safe defaults so little / no configuration should be required.
Building on your outline:
1. An Introduction to Whonix
a. What is Whonix
b. How is Whonix different from other Anonymity Distributions
2. Installation and Updating (Upgrading)
a. Choose a Virtualization Platform
* Hardware Requirements
* Host Recommendations
b. Download, verify
c. Install
3. First Steps in Whonix
a. Launch, connect
* censored? click link to main docs
b. Update
c. Browse the Web
d. Shutdown
4. Common Tasks
a. Pre-Installed Applications
b. Need something else? click link
5. Preserving Anonymity and Privacy
a. What to do & What not to do
6. Where to go from here (links)
a. multiple browsers/gateways/workstations
b. tunnels
c. other applications
d. hardened configurations
