Answer 1

In order to use new CakeEmail('gmail') you have to config gmail in your configure file (/Config/email.php) such as:
public $gmail = [
'transport' => 'Mail',
'from' => 'you#localhost',
//'charset' => 'utf-8',
//'headerCharset' => 'utf-8',
];
http://book.cakephp.org/2.0/en/core-utility-libraries/email.html
new CakeEmail('gmail') will read your gmail config and you will not have to configure it in your application.
If you do all your configuration in your application, perhaps you would like to use new CakeEmail();
