So I finally was able to test out the C-c C-c. It did ask me if I wanted to apply and I said yes. When I exported the file, my postamble (as specified in the variable) was not shown...it was still the default.

Strangely, when I did C-c C-c, Emacs came back with this:

The local variables list in syllabus.org
contains values that may not be safe (*).

Do you want to apply it? You can type
y -- to apply the local variables list.
n -- to ignore the local varialbes list.
! -- to apply.....

* org-html-postamble : t
* org-export-hml-postamble-format : "Hello World"

Notice the '*' warning not to be safe. But the source .org file is with '#' as it should be (seen further below).

Thoughts?

in my .org file and still no luck.

After you add this to the .org file, you need to refresh the setup.  I
do this by moving cursor to the top of the file (with all of the #+
lines) and pressing C-c C-c.  You should get a message asking if it is
OK to set local variables.  Pressing y should set org-html-postamble and
org-export-html-postamble-format for that buffer.
