How to make a simple script that copy a layer name and paste in a new text layer.

I hacked away at Chuck's script from the links above, not sure if this is helpful or not... I know there is a better (shorter) way to align a layer to the canvas edge/s, however, I only know how to do it as I would in an action (select all, align, deselect).

/* Initial setup */
var myDoc = app.activeDocument;
var myRulers = app.preferences.rulerUnits
app.preferences.rulerUnits = Units.PIXELS;

/* Text layer related stuff */
var myLayerName = 'PrefixTEXT - ' + myDoc.activeLayer.name + ' - SuffixTEXT'; // Remove the prefix/suffix as required
var myLayerText = myDoc.artLayers.add()
myLayerText.kind = LayerKind.TEXT
var myText = myLayerText.textItem
myColor = new SolidColor
myColor.rgb.red = 255
myColor.rgb.green = 0
myColor.rgb.blue = 0
myLayerText.textItem.color = myColor
myText.position = [0,20] // Upper Left
myText.justification = Justification.LEFT
myText.size = 12
myText.contents = myLayerName;
myLayerText.name = myLayerName // Or add a fixed string in quotes i.e. 'My Great Layer Name!'

/* Select All for the align steps */
myDoc.selection.selectAll();

/* Align to right edge of canvas */
alignRight(false);
function alignRight(alignToCanvas) {
	var c2t = function (s) {
		return app.charIDToTypeID(s);
	};

	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};

	var descriptor = new ActionDescriptor();
	var reference = new ActionReference();

	reference.putEnumerated( s2t( "layer" ), s2t( "ordinal" ), s2t( "targetEnum" ));
	descriptor.putReference( c2t( "null" ), reference );
	descriptor.putEnumerated( s2t( "using" ), s2t( "alignDistributeSelector" ), s2t( "ADSRights" )); // Right
	descriptor.putBoolean( s2t( "alignToCanvas" ), alignToCanvas );
	executeAction( c2t( "Algn" ), descriptor, DialogModes.NO );
}

/* Align to top edge of canvas */
alignTop(false);
function alignTop(alignToCanvas) {
	var c2t = function (s) {
		return app.charIDToTypeID(s);
	};

	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};

	var descriptor = new ActionDescriptor();
	var reference = new ActionReference();

	reference.putEnumerated( s2t( "layer" ), s2t( "ordinal" ), s2t( "targetEnum" ));
	descriptor.putReference( c2t( "null" ), reference );
	descriptor.putEnumerated( s2t( "using" ), s2t( "alignDistributeSelector" ), s2t( "ADSTops" )); // Top
	descriptor.putBoolean( s2t( "alignToCanvas" ), alignToCanvas );
	executeAction( c2t( "Algn" ), descriptor, DialogModes.NO );
}

/* Deselect */
myDoc.selection.deselect();

/* Move the layer in 5px */
myDoc.activeLayer.translate( -5, 5 );

/* Reset the ruler units */
app.preferences.rulerUnits = myRulers

Here are a couple of start points:
