Is the procedure similar if i wanted to do the same also for the "Documents" module?

yes

The "Documents" module has the option of selecting "Log the user, date, and time for every link click" and then displaying the log ("Display" ), is it possible to have the same user controls also for the "Repository" module?

no, not unless you add the code to do so, and the code to do that would not be quite as simple as just sending an email
