What is the entry point of an AS3 script?
Are there any good very simple tutorials on using Flash CS4 (Windows)?

There are two possibilities:
You override initializationComplete()
override protected function initializationComplete():void
Or you call a method in your script directly from somewhere in a Flash application...in which case there really is no entry point.
As for good tutorials, Adobe probably has the best:
Adobe - Flash Developer Center (look on the right hand nav bar for the tutorials)
If you specify a document class, the entry point would be the constructor of that class.
