Answer 1

Your validator structure is wrong.
The validators key is expecting an array of validators. You are supplying the validator name and options directly.
Change this:
this->add(array(
'name' => 'email',
'required' =>true,
'validators' => array(
'name' => 'EmailAddress',
'options' => array(
'domain' => true,
),
),
));
To:
this->add(array(
'name' => 'email',
'required' =>true,
'validators' => array(
array(
'name' => 'EmailAddress',
'options' => array(
'domain' => true,
),
)
//Another validator here ..
),
));
