SaveAs save the current active document.  If  you want the Jpeg  to be a particular  size the current document need to be the size you want to save.  If you doe not the degrade the current document in this  process.  Dupe the document Crop the duplicated document to a the centered  Aspect Ration image you want the jpeg to have. Then resample the crop  with Image sized to the size and resolution you the want the Jpeg to have. Save your Jpeg then close the duplicated resized document.
