Answer 1

As of the heading: create a new comma-separated line which contains all headings, e.g.
SQL> select '"Record ID"' ||','|| '"Inputted Date"' ||','|| '"Inputted By"' as heading from dual;
HEADING
-----------------------------------------
"Record ID","Inputted Date","Inputted By"
SQL>
and include it as the 1st line in the output file.
As of the ###### issue: are you sure it is a problem? What happens when you double-click in between columns B and C in Excel? That operation should adjust column B width so that it matches data width (so I'd expect actual data to be seen afterwards).
