Answer 1

You can do this by Magento Event/Observer

First,using payment_method_is_active disable on depends current quote product type.

Code for this:

Module config.xml code:

<global>
    <events>
    <payment_method_is_active>
        <observers>
            <paymentfilter_payment_method_is_active>
            <type>singleton</type>
            <class>yourmodel/observer</class>
            <method>filterpaymentmethod</method>
            </paymentfilter_payment_method_is_active>
        </observers>
    </payment_method_is_active>
    </events>
</global>

Observer code is:

<?php

class YOURNANESPACE_YOURMODULE_Model_Observer {

    public function filterpaymentmethod(Varien_Event_Observer $observer) {
        /* call get payment method */
        $method = $observer->getEvent()->getMethodInstance();

        /*   get  Quote  */
        $quote = $observer->getEvent()->getQuote();

        $result = $observer->getEvent()->getResult();
        if (empty($quote) || (null === $quote)) {
            return $this;
        }

        /* Disable Your payment method for   adminStore */
        if ($method->getCode() == 'YOUR_PAYMENT_METHOD_CODE') {
            foreach ($quote->getAllItems() as $item) {
                // get Cart item product Type //
                if ($item->getProductType() == 'YourProductType'):
                    $result->isAvailable = false;
                endif;
            }
        }
    }

}

Answer 2

for that you need to use magento payment_method_is_active event

I am assuming you know how to develop magento extension[If not then please check this answer you get whole module Write this code in your config.xml from app>code>codepool>namespace>package>etc

<global>
    ...
    <events>
        <payment_method_is_active>
            <observers>
                <paymentfilter_payment_method_is_active>
                    <type>singleton</type>
                    <class>PaymentFilter_Model_Observer</class>
                    <method>paymentMethodIsActive</method>
                </paymentfilter_payment_method_is_active>
            </observers>
        </payment_method_is_active>
    </events>
    ...
</global>

Create observer file app/code/codepool>namespace>package/Model/Observer.php

class namespace_package_Model_Observer {

        public function paymentMethodIsActive(Varien_Event_Observer $observer) {
            $event           = $observer->getEvent();
            $method          = $event->getMethodInstance();
            $result          = $event->getResult();
            $currencyCode    = Mage::app()->getStore()->getCurrentCurrencyCode();


                if($someTrueConditionGoesHere){
                    $result->isAvailable = true;
                }else{
                    $result->isAvailable = false;
                }

        }

    }

Have you look this I think this would bee solve your issue you just need to modify the methods.phtml file andfrom where you can got any quotes info and do the validations or conditions as well from the module by event - observer or by the modification in phtml file ?
