Answer 1

You should create menu and (submenu) in Admin Panel, but I think you already know that :) Later you add look and feel with CSS. I think you should do ti with CSS not PHP.

Answer 2

JSubMenuHelper is designed to be used in the Joomla! Administrator section, it's not made for the frontend.

If you really want to get to it, you need to include the file:

/administrator/includes/toolbar.php

Also you will have a bunch of missing CSS (js maybe also) files that you also need to include (form the admin template folder)

But I see no reasons what you want to use JSubMenuHelper in front-end. I would strongly advise against using it.
