Answer 1

For example If you want to add a static block outsite the cart total:

Add below code at checkout_cart_index handle after the cart_totals block in your theme/layout/checkout.xml like

<block type="checkout/cart_totals" name="checkout.cart.totals" as="totals" template="checkout/cart/totals.phtml"/>
<block type="cms/block" name="customblock" after="totals" >
    <action method="setBlockId"><block_id>myblock</block_id></action>
</block>

after that call this block in you cart.phtml file after closing tag of

"<div class="cart-totals">"

like:

<?php echo $this->getChildHtml('customblock') ?>

In your case you can create a phtml file for your block and can show as above.
