Thank you for cross posting that thread here. I was not aware of that thread until now. Perhaps a better title like “Personal Ubuntu DL box setup” for that thread will help in future discovery 
Aside from that, you are right, pretty much everything to setup on personal Ubuntu 16 LTS DL box is covered in that thread.
radek's post caught my attention there.
wget and run this file3 - this is a modified script from part1 v1 that includes everything for part1 v2 and also installs keras, this could potentially be useful to a person setting up their own box (I try to maintain it and it has been tested by a couple of people in the course)
I prefer his method as it helps to simplify the setup process using a shell script that we can pull in from some place and run in our DL box. The nice part about this approach is, the script will be maintained and updated (hopefully) as we progress along the course and avoid bit rot. But before that, we have to first install NVIDIA drivers by following your first link “how to install latest NVIDIA drivers in Linux”.
These are the commands that will be run when the shell script is executed in bash terminal:

Another nice thing about this script is, it also automate the step to setup fast.ai part 1 v2 specific environment configurations.
