You might want to move the "FIND A CITY/ROAD/PLACE" search field and Lat/Lon off the map since it is difficult to see on the map.Also if you put placeholder="FIND A CITY/ROAD/PLACE" in the input tag for your search field, "FIND A CITY/ROAD/PLACE" would show up in the search field, and you wouldn't need the text above the search field.
<input type="text" size="20" name="geocodeAddress" id="geocodeAddress" style="padding-right: 1px; font-weight: normal; font-family: Trebuchet MS, Arial, Helvetica, sans-serif;" onclick="formatGeocode();" onkeypress="return checkSubmit(event);" placeholder="FIND A CITY/ROAD/PLACE">
I really like the way your help looks. I thought the help icon was a bit difficult to locate (size, location.)Useful map. Thanks for sharing.
