Answer 1

Try this,
    app.findGrepPreferences = app.changeGrepPreferences = null;   
    app.findGrepPreferences.findWhat = "(.+?) - (\\d+)";   
    found = app.activeDocument.findGrep (true);  
    for (j = 0; j < found.length; j++)  
        found[j].select();  
        if(found[j].parentTextFrames[0].parentPage.name % 2 == 0 && found[j].parentTextFrames[0].appliedObjectStyle.name == "AA1") 
            found[j].texts[0].select();  
            app.changeGrepPreferences.changeTo = "$2 / $1"; 
            app.selection[0].changeGrep();  
    app.findGrepPreferences = app.changeGrepPreferences = null;
