Making a few pages viewable after adding code to functions.php

Hi,

Just trying out your plugin and having one or two problems.

//redirect to login or homepage if user is logged out or not a member
function my_template_redirect()
{
	global $current_user;
	$okay_pages = array(pmpro_getOption('billing_page_id'), pmpro_getOption('account_page_id'), pmpro_getOption('levels_page_id'), pmpro_getOption('checkout_page_id'), pmpro_getOption('confirmation_page_id'));

	//if the user doesn't have a membership, send them home
	if(!$current_user->ID
		&& !is_front_page()
		&& !is_page($okay_pages)
		&& !strpos($_SERVER['REQUEST_URI'], "login"))
	{
		wp_redirect(home_url("wp-login.php?redirect_to=" . urlencode($_SERVER['REQUEST_URI'])));
	}
	elseif(is_page()
			&& !is_front_page()
			&& !is_page($okay_pages)
			&& !$current_user->membership_level->ID)
	{
		//change this to wp_redirect(pmpro_url("levels")); to redirect to the levels page.
		wp_redirect(home_url());
	}
}
add_action('template_redirect', 'my_template_redirect');

1. I have added the code above to my functions.php and it works very well, however, I am having trouble adding those few pages that I still want to be accessible to visitors.

For instance, if a page is titled ‘Contact’ and has a slug of ‘contact’, how is this added. All of my attempts so far, have failed.

2. I have a couple of users on the site who do not need to pay but I would like to add them to the new members list, whereas at the moment, they are only listed in the normal WP users section. Can I add them manually somehow?

Thank you if anyone has the knowledge and can help.
