Makes sense, using the tor browser adds another level of seperation.

Absolutely.

Got two more points to add to your list.
Use a device exclusively for your grey activity and also obsfucate your internet connection, don't use home wifi if possible.

Thanks for the suggestion.

It's pretty much common sense, hence I didn't feel the need to add something to that effect at the time of writing my list.

It is common sense but the majority of people don't do it.
Plenty of people been tracked to their home wifi and caught.
