InDesign Workflow for DPS

Question

I've been working on this project for a while now and I wonder if anyone has any ideas or can point me to some resources about how to set up this script.
I recieve PDFs and I want to convert them to PNGs (using Photoshop) and then place them in an InDesign document. This is how I ideally see it happening.
I drag the PDF onto a app and the script creates a folder structure based on the file name.
filename_stack
- links
- original
Takes the PDF and convert it to a PNG, using Photoshop CS5 (in RGB, at 300 dpi)
Save the PNG as filename.png
Moves the PDF to "original" folder
Moves the PNG to "links" folder
Creates an InDesign document (746 px by 1024 px, for web use)
Places the PNG in the document, centered in frame that is 746 x 1024, with the picture at 130%
Saves the InDesign document in the "filename_stack" folder with the name "filename_v.indd"

Answer 1

I've actually made a lot of progress so far using applescript.
I have a script that makes all of the basic folders and moves the file into the right folder. Now on to having InDesign create a new document and place the file.
Here is what I have so far:
on open mgItems
  repeat with mgItem in mgItems
  tell application "Finder"
  set mgName to name of mgItem
  set mgExtension to name extension of mgItem
  set the mgFolderPath to (the container of mgItem) as text
  set text item delimiters of AppleScript to {"."}
  set mgNewName to text item 1 of mgName
  set text item delimiters of AppleScript to {"_"}
  set mgNewName to text item 1 of mgNewName
  set text item delimiters of AppleScript to ""
  set stackName to "_stack"
  try
  set mgFinalFolder to mgFolderPath & mgNewName & ":" as alias
  on error
  set mgFinalFolder to make folder at mgFolderPath with properties {name:mgNewName & (stackName)}
  end try
  set folder1 to make new folder at mgFinalFolder with properties {name:"original"}
  set folder2 to make new folder at mgFinalFolder with properties {name:"links"}
  move mgItem to mgFinalFolder
  move mgItem to folder2
  set the templateFile to "Macintosh HD:Users:jcavicchi:Desktop:scriptopia:donotmove.indd"
  set templateRename to duplicate templateFile to mgFinalFolder
  set extentionName to "_v.indd"
  set name of templateRename to mgNewName & (extentionName)
  end tell
  end repeat
end open
