Answer 1

Ok. Lets Go to your "billing.phtml" file Which is Located at

frontend\rwd\default\template\persistent/checkout/onepage/billing.phtml

And Paste Following Code If You want to Checkbox Field.

<div class="field">
    <input id="p_method_cashondelivery" value="cashondelivery" type="checkbox" name="cod" title="Cash On Delivery" onclick="<?php echo "checked!!!!";?>" class="checkbox" autocomplete="off">
    <label for="p_method_cashondelivery">Cash On Delivery </label>
</div>

Please place this code too at end line of your installer code after the " $attribute->save();" function call.

$installer->run("
    ALTER TABLE {$this->getTable('sales_flat_quote_address')} ADD COLUMN `license_number` VARCHAR(255) CHARACTER SET utf8 DEFAULT NULL AFTER `fax`;
    ALTER TABLE {$this->getTable('sales_flat_order_address')} ADD COLUMN `license_number` VARCHAR(255) CHARACTER SET utf8 DEFAULT NULL AFTER `fax`;
");
$installer->endSetup();
