Answer 1

you need to add the following in your html:
<meta name="csrf-token" content="{{ csrf_token() }}">
You should definitely take a look at this page to understand how this works: https://laravel.com/docs/5.2/routing#csrf-protection

Answer 2

The tokenMismatchException in VerifyCsrfToken.php line 53: error means that either your csrf token has expired or that you are not sending this to the server when doing a post request. I'm guessing the second.
When doing a ajax post request to the server you need to include a parameter _token in your data. You can get the current csrf token for this user using csrf_token().
Another option is to add X-CSRF-TOKEN header to your ajax setup. The Laravel documentation explains how to do this.
