Answer 1

You are running out of RAM that can be used by PHP. You can set how much RAM that PHP will use in php.ini. You currently have this limit set to 24MB, which is pretty low. Try increasing it.
ini_set('memory_limit', '256M');

Answer 2

PHPExcel is known for being memory hungry. The website has a discussions with some workarounds, see http://phpexcel.codeplex.com/discussions/242712?ProjectName=phpexcel
You could also consider using another library like the old Spreadsheet_Excel_Writer lib (which has its drawbacks as well)
