Add cover sheet without affecting existing page numbering?

Question

I guess the lack of response means either that my question is inappropriate in some way or else it's difficult or impossible to answer! Thanks for letting me post it anyway!
This seems to be a very informative site (just figured out how to access it and read the responses to all the questions), and I know I'll learn a lot from reading it in the future---so thanks on that account also.   ---JCI
ORIGINAL QUESTION:
Hi,
I have a script that inserts a new page (a cover sheet) at the beginning of a document (a chapter from a book) and makes a few other tweaks. It works perfectly _except_ for the following glitches:
(1) The pages shuffle (I would like the cover sheet to be a recto page and the first page of the document to be a recto page as well; the rest are facing pages ).
(2) The pages renumber (I would like to the cover sheet to be an invisible page number roman numeral "i" and the first page of the document to be page 1.1.
(3) If I just renumber the pages manually, I also have to retype all the section names that have been inserted previously into the section marker field (I have about 160 documents to work on, so....)
Is there any way to have the script avoid these problems? Please note that I inherited this script and know virtually nothing about scripting. Any help you can give—including any thoughts on whether coming up with such a script would even be possible—will be greatly appreciated!! Here is the script (and thanks in advance!):
var myFolder = Folder.selectDialog ("Choose a Folder");
var myFile;
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
if(myFolder != null){
    myFile = myFolder.getFiles();
    for(i=0; i<myFile.length; i++) {
        app.open(File(myFile[i]));
// insert page at beginning and apply master page
        app.activeDocument.pages.add(LocationOptions.AT_BEGINNING);
        var myMasterSpread = app.activeDocument.masterSpreads.item("C-WebP1");
        app.activeDocument.pages[0].appliedMaster = myMasterSpread;
// find and remove "[advanced release]" from document
          app.findChangeTextOptions.includeMasterPages = true;
          app.findChangeTextOptions.caseSensitive = false;
          app.findTextPreferences.findWhat = "[advance release]" ;
          app.changeTextPreferences.changeTo = " ";
          app.activeDocument.changeText();
          app.findTextPreferences = null;
          app.changeTextPreferences = null;
// determine if last page is blank and if so, delete
         var Lpage = app.activeDocument.pages.lastItem();
         if(Lpage.pageItems.length==0&&Lpage.guides.length==0){
                Lpage.remove();
// save and close file
        app.activeDocument.save(new File(myFile[i]));
        app.activeDocument.close();
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;

Try this,
var myFolder = Folder.selectDialog ("Choose a Folder");
var myFile;
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
if(myFolder != null){
    myFile = myFolder.getFiles();
    for(i=0; i<myFile.length; i++) {
        app.open(File(myFile[i]));
// insert page at beginning and apply master page
            var _page = app.activeDocument.pages.add(LocationOptions.AT_BEGINNING);
            var myMasterSpread = app.activeDocument.masterSpreads.item("C-WebP1");
            app.activeDocument.pages[0].appliedMaster = myMasterSpread;
            var section = doc.sections.add(_page);
            section.pageNumberStyle = PageNumberStyle.LOWER_ROMAN;
            var section1 = doc.sections.add(doc.pages.item(1));
            section1.continueNumbering = false;
            section1.pageStart = doc.pages.item(1);
            section1.pageNumberStart = 1;
            section1.sectionPrefix = "1."
            section1.pageNumberStyle = PageNumberStyle.ARABIC
// find and remove "[advanced release]" from document
          app.findChangeTextOptions.includeMasterPages = true;
          app.findChangeTextOptions.caseSensitive = false;
          app.findTextPreferences.findWhat = "[advance release]" ;
          app.changeTextPreferences.changeTo = " ";
          app.activeDocument.changeText();
          app.findTextPreferences = null;
          app.changeTextPreferences = null;
// determine if last page is blank and if so, delete
        var Lpage = app.activeDocument.pages.lastItem();
        if(Lpage.pageItems.length==0&&Lpage.guides.length==0){
                Lpage.remove();
// save and close file
        app.activeDocument.save(new File(myFile[i]));
        app.activeDocument.close();
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
