I'm not sure about Problem 2 but regarding Problem 1, you need to trap an AppleEvent in order for a standalone to perform some activities before quitting. For example, put this script in your main stack script and when theClass = "aevt" and theID = "quit", you can successfully trap the program before it quits. eg.
on appleEvent theClass,theID
if theClass = "aevt" and theID = "quit" then
-- do something
