Regarding the lists, do you have a wiki you have seen do this? As far as I am aware, it is not possible to retrieve which categories are most visited/popular and whatnot. Yes, there are special pages that do stuff like that but they are using data that, as far as I know, is not accessible to us as users.

What do you mean by "JavaScript formatting"? Do you mean inserted using JavaScript? There are a few solutions already available on the dev wiki; perhaps one will be suitable for your purposes. In no particular order:
 * Digital Clock
 * UTCClock
 * Countdown
 * TZclock
 * DisplayTimer
