Answer 1

Not sure that you can read submitted values from hook_form_alter() directly. Instead I think that you should add (register) your custom submission form handler from there:

$form['#submit'][] = 'my_custom_submit_handler';

And then make another function called that way ("my_custom_submit_handler()"), so when form is submitter your custom submission form handler will be also called and you can collect password data and save it.

What you can do is:

Setting the password to a random value, using user_hash_password()
Show a message to the users telling them they need to reset their password
The right way to call user_hash_password() is the following one.

require_once DRUPAL_ROOT . '/' . variable_get('password_inc', 'includes/password.inc');
$hash = user_hash_password($password);
