Answer 1

It's always a good idea to close resources you use, BUT:

If you use resource A in resource B, it's sensible to close B instead of A if it has a method for it.

In your case, you use FileInputStream in Workbook, so you'd better to close Workbook and rely on Workbok that it will close FileInputStream.

In this particular case, actually, Workbook will close FileInputStream at the end of the getWorkbook() method but it's still a good idea to close Workbook to be able to be garbage collected.
