Here is line 180 to put both the address_about and the street address together. There is a space between the 'address_about' and 'street'. If one of the fields is blank it just won't be there.
If you want a dash or other separator put it between the 1st 2 single quotes. Such as this if you want a - between them. CONCAT_WS('-',
CONCAT_WS(' ',`$GLOBALS[mysql_prefix]ticket`.`address_about`,`$GLOBALS[mysql_prefix]ticket`.`street`) AS ticket_street,
I also changed the length to 60 on line 238
$address_street=htmlentities(shorten(stripslashes($row['ticket_street'] . " " . $row['ticket_city']), 60), ENT_QUOTES);
