How do I draw a line across a form & how do I right justify my text fields when I put labels to the left and fields to the right

You can add the Form Separator widget to get the Line across the form

On regards to label aligning, simply click on Label align button from the toolbar. That should work.

Otherwise you might try injecting this Custom CSS codes

.form-line  {
  clear:both !important;
}

.form-label-left {
  float: left !important;
}
