A few things that bothers me:
<script language="JavaScript" type="text/JavaScript">

You don't need Language and type, here. You can either use
<Script Language = "JavaScript">
or
<Script Type = "text/JavaScript">
only!.
The latter <Script Type = "text/javascript"> is the preffered way these days, because the Language attribute of the Script tag is going to fall away.

Then
function MM_openBrWindow(theURL,winName,features) { //v2.0
window.open(theURL,winName,features);
}
This, at the end of the day is, in my opinion, unecessary. The JavaScript Object Model has the open method built in for the window object, which contains the parameters URL, name, and features already.
