$collection->getSelect()->join('sales_flat_order_item', '`sales_flat_order_item`.order_id=`main_table`.entity_id', array('name'  => new Zend_Db_Expr('group_concat(`sales_flat_order_item`.name SEPARATOR ", ")')));

        'index' => 'name',
    ));

Take look at Show SKU and Product Name in Sales_Order_Grid?

You can do this one of two ways :

1) Using "renderer"

$this->addColumn('name', array(
    ....                                        
    'renderer' => 'NameSpace_ModuleName_Block_Adminhtml_Renderer_Productsname',          
));


class NameSpace_ModuleName_Block_Adminhtml_Renderer_Productsname extends     Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{
    public function render(Varien_Object $row)
    {                    
        $order=Mage::getModel('sales/order')->load($row->getData('entity_id'));              
        $str="";

        foreach($order->getAllVisibleItems() as $_item){                      
            $str .= $_item->getSku();
    }       
        unset($order);
        return $str;
    }
}

2) using "join" see https://magento.stackexchange.com/a/14343/519
