Answer 1

This is not an error message, it's just debug output. Disable it by setting $mail->SMTPDebug = 0;.
PHPMailer 5.2.6 is very old and buggy. Get the latest version and base your code on one of the examples you'll find on there too.
Also, please learn how to format your question so that it's actually readable.
