Answer 1

I'd create local.xml file inside your theme folder app/design/frontend/[your_package]/[your_theme] (if you haven't already)
And insert the following lines there
<?xml version="1.0"?>
<layout version="0.1.0">
<catalog_product_view>
<reference name="product.info.tabs">
<action method="unsetChild">
<child>product_additional_data</child>
</action>
</reference>
</catalog_product_view>
</layout>
After that clear the cache.
If you prefer to edit XML in separate files (which I'm not), find catalog.xml of your theme.
find the following line and comment them (<!-- -->)
<action method="addTab" translate="title" module="catalog"><alias>additional</alias><title>Additional Information</title><block>catalog/product_view_attributes</block><template>catalog/product/view/attributes.phtml</template></action>

Answer 2

Are you create new attribute for product description .remove any one of the product attribute.
you can remove your attribute in your magento admin page .
Catalog->attributes->manage attributes
select your attribute you want to delete.
OR
open your attribute check "Visible on Product View Page on Front-end" change yes to no

I am using my module adminhtml layout xml to add or remove tabs (you could use your theme's local.xml, based on these steps with a bit of tweakking.)
Firstly you will need to declare your layout updates (in your module config.xml) like the following:
<adminhtml>
<layout>
<updates>
<mymodule>
<file>mymodule.xml</file>
</mymodule>
</updates>
</layout>
</adminhtml>
Then in mymodule.xml, add the following (here, I am using the admin order view page handle)
<adminhtml_sales_order_view>
<reference name="sales_order_tabs">
<action method="removeTab">
<name>order_shipments</name>
</action>
<action method="addTabAfter">
<name>order_shipments_mymodule</name>
<block>mymodule/adminhtml_order_shipments</block>
<after>order_creditmemos</after>
</action>
<action method="addTab">
<name>order_receipts</name>
<block>mymoduled/adminhtml_order_recp</block>
</action>
</reference>
</adminhtml_sales_order_view
