Batch subfolder images to layer stacks, then to sprites.

Question

I have tried for nearly a week now to wrap my head around this one but I'm a just too new to java scripting to pick it up soon enough to solve my problem. I found Batch HDR creation script, which was great and close to what I'm looking for but I'm not sure how to put it all together. I'm hoping, no begging for some help.
Ok....
So I have animations for a game rendered into png image sequences placed into separate folders that contain customizable armor and weapons that can be added on top of the character upon the gamers selection.
There are 130 total character animation folders and 209 separate subfolders inside the animation folders containing the custom armor and weapons following the character.
The original idea was just to give the programer image sequences but it has changed to require sprite sheets now, and that leaves way too many manual conversions to cover in the time I'm allotted.
I need a script that makes you browse for the top folder(the animation)one time then opens all subfolder images one folder at a time into layer stacks, then converts them to sprite sheets, saves them out as a png with transparency to a separate folder containing all created sprite sheets from the animation folder in one new folder or already created folder on the desktop.
I mashed some well thought out(not mine) scripts together but couldn't get them to batch open subfolders and the layers to sprite would return an error because some frames are blank.
I'm using Photoshop CS5 and Mac osx, this is my first forum post anywhere, ever, so exciting. Thanks for any advice or help.

// select folder, create files with the contents of one of the subfolders each as layers and save them to the folder;
// use it at your own risk;
#target photoshop
// select a folder;
var sourceFolder = Folder.selectDialog("Select folder");
if (sourceFolder) {
// the psd options;
psdOpts = new PhotoshopSaveOptions();
psdOpts.embedColorProfile = true;
psdOpts.alphaChannels = false;
psdOpts.layers = true;
psdOpts.spotColors = true;
// get the contents as one array per folder;
var items = retrieveFiles(sourceFolder, [[]]);
// iterate through;
for (var m = 1; m < items.length; m++) {
          var thisArray = items[m];
          var folderName = thisArray[0].parent.name;
