Amazing what a day's rest can accomplish
All figured out!
What I did was add the field I needed in AdminDB.class.php on line 76, then went to admin.template.php and on line 785 I added this code to allow it to appear.
<td width=\"10%\">" . $link->getLink($_SERVER['PHP_SELF'] . $util->getSortingUrl($_SERVER['QUERY_STRING'], 'location'), translate('Location')) . "</td>
Then beneath that between line 807 and 809 I added this . '<td style="text-align: left">' . $cur['streetaddress'] . "</td>"
I had to sit down with pen/paper to map how everything is called together, in order to keep track of everything, it helped
