Answer 1

As i check you have already display form for add review in tab so this tab just need to show review. so please check below code.

<?php $_items = $this->getReviewsCollection()->getItems();?>
<div class="box-collateral box-reviews" id="customer-reviews">
<?php if (count($_items)):?>
    <div class="review-heading">
        <h2>
            <?php echo $this->__('') ?>
            <span class="reviewtab">

                <tbody>

                    <?php foreach ($_votes as $_vote): ?>
                    <tr>
                        <th><?php echo $this->escapeHtml($_vote->getRatingCode()) ?></th>
                        <td>
                            <div class="rating-box">
                                <div class="rating" style="width:<?php echo $_vote->getPercent() ?>%;"></div>
                            </div>
                        </td>
                    </tr>
                    <?php endforeach; ?>
                </tbody>
            </table>
            <?php endif; ?>
            <a href="<?php echo $this->getReviewUrl($_review->getId()) ?>">
                <?php echo $this->escapeHtml($_review->getTitle()) ?>
            </a>
        </dt>
        <dd>

            <?php echo nl2br($this->escapeHtml($_review->getDetail())) ?>




            <span class="review-meta">
                <?php echo $this->__('Review by %s', $this->escapeHtml($_review->getNickname())) ?>
                /
               <?php echo $this->__('(Posted on %s)', $this->formatDate($_review->getCreatedAt()), 'long') ?>
            </span>
        </dd>
    <?php endforeach; ?>
    </dl>
 <?php else: ?>
   <div class="review-heading"><?php echo $this->__('No rating Available'); ?></div>
 <?php endif; ?>
</div>

Answer 2

Just replace:

<?php elseif($this->getParentBlock()): ?>
    <?php echo $this->getParentBlock()->getReviewsSummaryHtml($this->getProduct(), 'short', true)?>
<?php endif;?>

with:

<?php elseif($this->getParentBlock()): ?>
    <?php echo $this->__('No rating Available');?>
    <?php echo $this->getParentBlock()->getReviewsSummaryHtml($this->getProduct(), 'short', true)?>
<?php endif;?>

If you also don't want to show Be the first to review this product, then comment out:

<?php echo $this->getParentBlock()->getReviewsSummaryHtml($this->getProduct(), 'short', true)?>
