Answer 1

IBM Worklight ships with Apache Cordova, you can try to use Cordova's Event API. Specifically the pause event.
This is an event that fires when a Cordova application is put into the background.
//Add the event listener
function wlCommonInit() {
document.addEventListener("pause", onPause, false);
}
// Handle the pause event
function onPause() {
//...
}

Answer 2

When you quit the app, the app quits. Nothing else happens.
Otherwise, you'll need to edit your question and be clearer.
Do you mean:
when the app quits
how to programmatically quit the app
what happens when the app moves to the background
something else...?
Availability:
Android
Windows Phone 7.5
Windows Phone 8
Edit: based on the comment to this answer, you want to use WL.App.overrideBackButton, so that once tapping on the physical Back button instead of quitting the app you could display a WL.SimpleDialog or alert or whatever else you want to do. An 'OK' button could then trigger WL.App.close to quit the application (and a 'Cancel' button that will do nothing, to keep the user in the app).
