Answer 1

You should close your $workbook object before trying to do anything with the file.
From the documentation:
An explicit close() is required if the file must be closed prior to performing some external action on it such as copying it, reading its size or attaching it to an email.

Answer 2

Try a slight modification on your code. Instead of
$ftp->put("TestRPT.xls");
Create another file in the www directory and try to ftp that file. If that file is called test.txt, change your line to:
$ftp->put("TestRPT.xls");
Thus, the only change in your code is the name of the file being FTP'd. If your FTP works, the problem isn't with the FTP, but with the Spreadsheet::WriteExcel module. As Mat has already stated, you need to do an explicit close on your object.
If your FTP doesn't work, it probably is an issue with the FTP call (although it looks fine to me).
