Answer 1

Go to product view page

app/design/frontend/Your-namespace/Your-theme/template/catalog/product/view.phtml

Put your description block code between below condition:

if($_product->getDescription()){
  //description block goes here
}

Answer 2

The file can be found here: /app/design/frontend/[theme name]/[package name]/template/catalog/product/view/attribute.phtml

Open the file and search for the following lines:

    <?php foreach ($_additional as $_data): ?>
<tr>
    <th class="label"><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
    <td class="data"><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
</tr><?php endforeach; ?>

Replace the entire foreach loop with the following lines of code:

<?php foreach ($_additional as $_data): ?>
    <?php $_attribute = $_product->getResource()->getAttribute($_data['code']);
    if (!is_null($_product->getData($_attribute->getAttributeCode())) && ((string)$_attribute->getFrontend()->getValue($_product) != '')) { ?>
    <tr>
        <th class="label"><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
        <td class="data"><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
    </tr>
    <?php } ?>
<?php endforeach; ?>

<?php foreach ($_additional as $_data): ?>
    <?php $_attribute = $_product->getResource()->getAttribute($_data['code']);
    if (!is_null($_product->getData($_attribute->getAttributeCode())) && ((string)$_attribute->getFrontend()->getValue($_product) != '')) { ?>
    <tr>
        <th class="label"><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
        <td class="data"><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
    </tr>
    <?php } ?>
<?php endforeach; ?>
