inDesign Document Conversion

I have a large number of similarly-formatted documents that need to be rebranded. I require a VB Script to be executed in inDesign that will perform simple formatting changes and replace master items. Most of the script is already written. But I cannot figure out how to accomplish the two items shown as incomplete below... Required formatting changes: a) Replace a color [done] b) Replace text [done] c) Revise metadata (document information) [done] Replace master items a) Select and delete specific master items [INCOMPLETE] b) Open a Source indd file [done] c) Copy master items [done] d) Paste copied items into the target document [done] e) Close Source document [done] Add a one-character prefix to the document name and apply it to: a) Master Page footers [done] b) Metadata [done] c) Document file name [done] Adjust the rule above the footer paragraph to accomodate the extra character [INCOMPLETE] Save the document to the same folder with the one-character prefix [done] The winning bidder will complete these two items and integrate them into the existing script. Attached are sample documents and in the incomplete script.
