How to move and resize a whole layer with different objects and groups

Question

Ok, I am a bit confused here.Things are not working like I thought they would and the documentation has confused me more.
currently in my code I have
var embedLeftSleeve = new File(folderPath+"/LeftSleeve.ai");
var leftSleevePlaced = doc.groupItems.createFromFile(embedLeftSleeve);
                        leftSleevePlaced.top = currentHeight;
                        leftSleevePlaced.left = 0;
I am importing an AI file and trying to put it into its own layer. I want it (the imported ai file) into into it's own layer. And I would like the layer to be setup the exact way it was in the original. But, after the import it seems to group non-grouped items, some of the objects are not showing the same way they did (like a shape with a gradient fill in it).
And finally, I want to scale all of the items in that layer as if I selected the layerer in illustrator and scaled it by hand (but scripting it to a set scale).
Can someone please help me. I am digging deep into the documentations and looking all over online to find what I want with little luck.

Any chance of a sample of your art? I had a quick and my test art does NOT break up or look any different.
I've been trying to build myself a set of library functions so my methods may appear a little odd.
This was fine for me…
#target illustrator
var sleveArt = new File ('~/Desktop/Untitled-2.ai');
var artName = sleveArt.name;
var docRef = app.activeDocument;
with (docRef) {
pageOrigin = [0,0];
rulerOrigin = [0,0];
var docHeight = height;
myLayer = layers.add();
myLayer.name = artName;
myGroup = myLayer.groupItems.createFromFile(sleveArt);
myGroup.top = docHeight;
myGroup.left = 0;
resizeObject(myGroup, 140, 140, 100, 'BL');
selection = null;
function resizeObject(obj, sX, sY, clw, tr) {
if (verifyObject(obj)) {
var transAbt = getAnchor(tr);
obj.resize(sX, sY, true, true, true, true, clw, transAbt);
return true;
function verifyObject(obj) {
if (obj.typename == 'CompoundPathItem'||'GraphItem' || 'GroupItem' || 'PathItem' || 'PlacedItem' || 'PluginItem' || 'RasterItem' || 'SymbolItem' || 'TextFrame') return true;
else return false;
function getAnchor(x) {
var thisTrans;
switch(x) {
case 'B' : thisTrans = Transformation.BOTTOM; break;
case 'BL' : thisTrans = Transformation.BOTTOMLEFT; break;
case 'BR' : thisTrans = Transformation.BOTTOMRIGHT; break;
case 'C' : thisTrans = Transformation.CENTER; break;
case 'DO' : thisTrans = Transformation.DOCUMENTORIGIN; break;
case 'L' : thisTrans = Transformation.LEFT; break;
case 'R' : thisTrans = Transformation.RIGHT; break;
case 'T' : thisTrans = Transformation.TOP; break;
case 'TL' : thisTrans = Transformation.TOPLEFT; break;
case 'TR' : thisTrans = Transformation.TOPRIGHT; break;
return thisTrans;
