I figured out the listbox question. The code I used is...

<script language="javascript">
function GetListBoxValue(MyItem)
{
	var oListBox = document.getElementById("ListBoxReminderTimes")
	return oListBox.options[MyItem].value
}
</script>

Since the HTML isn't generated for controls that have their Visible set to False, I ended up with a listbox that's 1 pixel by 1 pixel... It's a work around, but it worked.
