Custom TKB Article Pages and Styling

I am looking at using the TKB setup to create an area that will house detailed information about some of our lead users in the company for an internal-only category. I would like to custom the TKB article page to display the information on a single row so I can have more room available and look at the possibilities of adding custom components to share some detailed information about the user from inside the Community, such as their recent messages and time online for a quick snapshot of the users overall activity.

My first question: What is the naming scheme to override a TKB article page for the specific TKB?

My second question: What would be the best way to pull the users information dynamically for 20+ different users? Should I create an endpoint to gather this data? Any tips?
