Answer 1

1- This tutorial may help you, it does exact the same thing you want but just for customer account Add Custom Field to Customer Address

2- Another rough method is that you override the magento core files,

-> app/code/core/mage/adminhtml/block/permissions/users/edit/tab/main.php

and add your desired field and then goto database admin_user table and add that field there

Answer 2

You will need to add a column to the admin_user table.

$installer->getConnection()->addColumn($installer->getTable('admin/user'), 'location', array(
    'type' => Varien_Db_Ddl_Table::TYPE_TEXT,
    'length' => 256,
    'nullable' => true,
    'default' => null
)); 

Then, if you want to add/edit this field from the backend you need to rewrite the method Mage_Adminhtml_Block_Permissions_User_Edit_Tab_Main::_prepareForm and add a new element in there:

        $fieldset->addField('location', 'select', array(
            'name'      => 'is_active',
            'label'     => Mage::helper('adminhtml')->__('location'),
            'id'        => 'is_active',
            'title'     => Mage::helper('adminhtml')->__('location'),
            'class'     => 'input-select',
            'style'     => 'width: 80px',
            'options'   => array('1' => Mage::helper('adminhtml')->__('Yes'), '0' => Mage::helper('adminhtml')->__('No')),
        )); 

Clear the cache and it should work.
