I think bb_cookie is in pluggable.php, so yes. Just look for wordpress documentation on overwriting functions like this (achieveable through plugins).

Also easy.

add_action('bb_init', 'chuck_out_lusers');

function chuck_out_lusers() {

if( !bb_get_current_user() && bb_get_location != 'login-page' ) {

header('Location: http://blah.example.com/bb-login.php');

exit;

}

}
