I am copying to the mapserver list so that others may contribute
and/or benefit from our discussion.

To eliminate the "redraw map" link, you define a legend handler like this:

function legendHandler(name, state) {
   ms.setLayer(name, state);
   ms.draw();
}

To set the initial state of layers, you call the changeNodeStatus()
function. In my window.onload() function I use the following code:

var slayers = ms.getLayers(",")
var alayers = slayers.split(",");
for(var i=0; i<alayers.length; i++)
    legend.changeNodeStatus(alayers[i], "on");

The teton county dBox site is not done, but one that is a little
further along is here:
