            body { font: normal 10pt Helvetica, Arial; }
            #map { width: 100%; height: 100%; border: 0px; padding: 0px; }
        </style>

            var iconOffset = new OpenLayers.Pixel(-(iconSize.w / 2), -iconSize.h);
            var icon = new OpenLayers.Icon("img/fourmarker.png",
                           iconSize, iconOffset);

            var zoom, center, currentPopup, map, lyrMarkers;
            var popupClass = OpenLayers.Class(OpenLayers.Popup.FramedCloud, {

That's really an OpenLayers question rather than an OSM one.

There are a bunch of OpenLayers mailing lists described here, and other useful resources, including an OpenLayers IRC channel, here.
