Adobe Extendsript Photoshop Script

I am attempting to create an Adobe Extendscript javascript to run on a folder of PSDs. I need it to: 1. Replace image Metadata with an existing Metadata Template called "UsageTerms". 2. Play an existing Action "Prep_PrintRes". (The action sharpens and converts to 8-bit) 3. Append "_PrintRes" to the filename. (ie [login to view URL]) 4. Save the file as a 12 Quality JPEG to specific folder on my hard drive, "D:/Transfer". 5. Play an existing Action "Prep_Magazine" (The action resizes, sharpens, and converts to CMYK) 6. Append "_Magazine" to the filename. (ie [login to view URL]) 7. Save the file as a 10 Quality JPEG WITH NO EMBEDDED PROFILE to "D:/Transfer". 8. Play an existing Action "Prep_Screen". (The action sizes, sharpens, and converts to sRGB) 9. Append "_ScreenRes" to the filename (ie [login to view URL]) 10. Save the file as an 8 Quality JPEG to "D:/Transfer" This must be in javascript. Thank you.
