Answer 1

Add <backend_model> tag in to your field.

Backend Model – a class which allows to operate with configuration data on the different stages (save, load).

It contains three major methods respectively for each event: _afterLoad(), _beforeSave() and _afterSave().

So you can use _afterSave() method.

Eg :

<addresses>
    <label>Blocked Email Addresses</label>
    <backend_model>yourmodule/system_config_backend_yourfile</backend_model>
    <sort_order>2</sort_order>
    <show_in_default>1</show_in_default>
    <show_in_website>0</show_in_website>
    <show_in_store>0</show_in_store>
</addresses>

Backend Model Class :

<?php

class Namespace_YourModule_Model_System_Config_Backend_Yourfile extends Mage_Core_Model_Config_Data
{
    protected function _afterSave()
    {
        if (is_array($this->getValue())) {
            /* You can perform your logic here */
        }
    }
}
