Newbie - How do I instantaneity an object from the current Project Library?

You'll need to associate that Library asset with a linkage class.
Right-click/Command-click and choose Linkage, then select "Export for
ActionScript" to enable the class field. Flash will automatically populate
the field with a name that closely matches the asset's library name. If you
like, you may change this class name as you please. If the asset is a movie
clip, you'll see that the base class is MovieClip; if it's a bitmap, you'll
see that the base class is BitmapData, and so on.

The way to instantiate the asset depends on the sort of class it is.
For movie clips, it's as easy as:

var myClip:YourClassName = new YourClassName();

... where "YourClassName," of course, matches whatever linkage class name
you gave the asset in the Library. Because it extends MovieClip -- in this
example -- your instance supports all the features of that class, such as x
and y properties:

myClip.x = 400;
myClip.y = 240;

... and then, because this is a visual asset, you have to add it to the
display list:

addChild(myClip);

... and you're done. If it's an audio file, you would instantiate it the
same as any Sound instance. If it's a bitmap, you would have to associate
it with a Bitmap instance. But this might just be a font or some other
asset, so it all depends.

What have you got? :)
