Answer 1

Because ZF2 ViewModel is tree structure, the layout actually is the root node of ViewModel, the ViewModel in your controller will be add as a child node of layout.

You could access layout ViewModel by access MvcEvent, try this in your controller:

public function indexAction()
{
    $events = $this->getServiceLocator()->get('Application')->getEventManager();
    $events->attach(MvcEvent::EVENT_RENDER, array($this, 'setVariableToLayout'), 100);
}

public function setVariableToLayout($event)
{
    $viewModel = $this->getEvent()->getViewModel();
    $viewModel->setVariables(array(
        'testvar' => 'bla',
    ));
}
