In your info.php add the following function to get the url of the news item.

public function getItemUrl($newsItem)
{
    return $this->getUrl('*/*/view', array('id' => $newsItem->getId()));
}

In your controller add following function to view the news detail page.

 public function viewAction()
  {
       $model = Mage::getModel('magentostudy_news/news');
       $model->load($newsId);
       $this->loadLayout();
       $itemBlock = $this->getLayout()->getBlock('news.info');
       $this->renderLayout();

  }

By doing this you can simply access the info page attaching this link on read more like

 foreach ($this->getCollection() as $newsItem)
 {
 //Other Code
 <a href="<?php echo $this->getItemUrl($newsItem) ?>">Read More..</a>
 }
