Some information you are asking for can be inserted easily, because most of the Quizzing system variables are updated after all questions. You can insert them in a text container. I have several examples on my blog. List with system variables for Captivate 6 (you don't tell the version you are using): http://blog.lilybiri.com/system-variables-in-captivate-6
For some other info you'll have to create user variables and calculate with an advanced action (number of questions remaining...).
But I don't understand which 'time' you want to display? Have a look at these posts:

And how will you display that scoreboard? Permanently or 'on demand' by clicking/rollover? In that case:
