Answer 1

$objPHPExcel->getActiveSheet()->getStyle("A1:".$objPHPExcel->getActiveSheet()->getHighestDataColumn()."1")->getFont()->setBold(true);

I found this to be a working solution, you can replace the two instances of 1 with the row number. The HighestDataColumn function returns for example C or Z, it gives you the last/highest column that's in the sheet containing any data. There is also getHighestColumn(), that one would include cells that are empty but have styling or are part of other functionality.
