Magento Custom Forms

Question

I'm trying to build my own Request Catalog Form in Magento, heavily based on the Contacts module that comes out of the box. I've set up my XML files:

1. ./app/etc/modules/RequestCatalog_RequestCatalog.xml
2. ./design/frontend/default/{theme}/layout/requestcatalog.xml
3. ./code/local/{namespace}/{module}/etc/config.xml

In my config.xml, I set my frontname to 'requestcatalog' and told it to use my module's controller. However, when I visit http://app.com/requestcatalog I receive the error:

Fatal error: Call to a member function setFormAction() on a non-object in /path/to/root/public_html/app/code/local/RequestCatalog/RequestCatalog/controllers/IndexController.php on line 55

Line 55 of IndexController.php looks like:

$this->getLayout()->getBlock('requestcatalog')->setFormAction( Mage::getUrl('*/*/post') );

I have my block named 'requestcatalog' defined in my layout XML.

I've searched SO and found a user w/ the same problem, however no solution was provided: http://stackoverflow.com/questions/1098518/magento-custom-module-fatal-error-call-to-a-member-function-setformaction

My requestcatalog.xml:

<layout version="0.1.0">
<default>
    <reference name="footer_links">
        <action method="addLink" translate="label title" module="requestcatalog" ifconfig="requestcatalog/requestcatalog/enabled"><label>Request a Catalog</label><url>requestcatalog</url><title>Request a Catalog</title><prepare>true</prepare></action>
    </reference>
</default>

<requestcatalog_index_index>
    <reference name="root">
        <action method="setTemplate"><template>page/2columns-right.phtml</template></action>
        <action method="setHeaderTitle" translate="title" module="requestcatalog"><title>Request a Catalog</title></action>
    </reference>
    <reference name="content">
        <block type="core/template" name="requestcatalog" template="requestcatalog/form.phtml"/>
    </reference>
</requestcatalog_index_index>

My IndexAction():

   public function indexAction()
{
    $this->loadLayout();

    $this->getLayout()->getBlock('requestcatalog')
        ->setFormAction( Mage::getUrl('*/*/post') );

    $this->_initLayoutMessages('customer/session');
    $this->_initLayoutMessages('catalog/session');
    $this->renderLayout();
}
