For #2, its another 2 line change to add an ID to the title and append 
that to the dragIcon...

23: return '<span id="title_'.$row['uid'].'" ondragstart....

117: 	document.getElementById("dragIcon").innerHTML = 
document.getElementById("drag_"+dragID).innerHTML + 
document.getElementById("title_"+dragID).innerHTML;
