I am trying to add a Google map to my site. I find dozens of examples but to get two separate methods to work on one page is beyond my cut and paste skills and need help. The example for my markers that I am totally happy with is:
Code:

var infowindow = null;
    $(document).ready(function () { initialize();  });

    function initialize() {

        var centerMap = new google.maps.LatLng(39.828175, -98.5795);

        var myOptions = {
            zoom: 6,
            center: centerMap,
            mapTypeId: google.maps.MapTypeId.ROADMAP

        var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

        setMarkers(map, sites);
	    infowindow = new google.maps.InfoWindow({
                content: "loading..."
            });
		
        var bikeLayer = new google.maps.BicyclingLayer();
		bikeLayer.setMap(map);
    }

    var sites = [
	['Mount Evans', 39.58108, -105.63535, 4, 'This is Mount Evans.'],
	['Irving Homestead', 40.315939, -105.440630, 2, 'This is the Irving Homestead.'],

	['Flatirons in the Spring', 39.99948, -105.28370, 3, 'These are the Flatirons in the spring.']
];



    function setMarkers(map, markers) {

        for (var i = 0; i < markers.length; i++) {
            var sites = markers[i];
            var siteLatLng = new google.maps.LatLng(sites[1], sites[2]);
            var marker = new google.maps.Marker({
                position: siteLatLng,
                map: map,
                title: sites[0],
                zIndex: sites[3],
                html: sites[4]
            });

            var contentString = "Some content";

            google.maps.event.addListener(marker, "click", function () {
                // alert(this.html);
                infowindow.setContent(this.html);
                infowindow.open(map, this);
            });
        }
    }
</script>

<div id="map_canvas" style="width:100%; height:100%"></div>

To this I would very much like to add some polylines to define an area, my example:
Code:
<!--From https://developers.google.com/maps/documentation/javascript/overlays#Polylines with LatLing , path  and var changed-->
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Polyline example</title>
   <style type="text/css">
      html { height: 100% }
      body { height: 100%; margin: 0; padding: 0 }
      #map_canvas { height: 100% }	  
	</style>
	
    <script type="text/javascript"
      src="http://maps.googleapis.com/maps/api/js?key=AIzaSyBIoVMQPWUr5IjMi5f3mexwOhCA17d093A&sensor=false">
    </script> 
    <script type="text/javascript"> 
      window.onload = loadMap;
      function loadMap() {
        var latLong = new google.maps.LatLng(39.828175, -98.5795);
        var mapOptions = {
          zoom: 6,
		  mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
    },
    zoomControl: true,
    zoomControlOptions: {style: google.maps.ZoomControlStyle.SMALL
    },
          mapTypeId: google.maps.MapTypeId.ROADMAP,
          center: latLong
        };

        var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
        var polyline = [
        new google.maps.LatLng(39.58108, -105.63535),
        new google.maps.LatLng(40.315939, -105.440630),
        new google.maps.LatLng(43.785890, -101.90175),
       	new google.maps.LatLng(39.99948, -105.28370),
		
      	
    ];
    var redline = new google.maps.Polyline({
      path: polyline,
      strokeColor: "#FF0000",
      strokeOpacity: 1.0,
      strokeWeight: 2
    });

   redline.setMap(map);
  }
</script>
  </head>
  <body>
    <div id="map_canvas"></div>
  </body>
</html>
Can anyone tell (show) me how to add this concept to my markers example. Or... if these are totally incompatible methods and I am wasting my time trying.

Thank you for your time
