Answer 1

Take a look at the Tax-meta-class developed to add extra fields to taxonomies: WordPress Taxonomies Extra Fields the easy way

1) Include the main class file

require_once("Tax-meta-class/Tax-meta-class.php");

2) Configure taxonomy custom fields

$config = array(
    'id' => 'demo_meta_box',
    'title' => 'Demo Meta Box',
    'pages' => array('category'),
    'context' => 'normal',
    'fields' => array(),
    'local_images' => false,
    'use_with_theme' => false
);

3) Initiate your taxonomy custom fields

$my_meta = new Tax_Meta_Class($config);

4) Add fields

//text field
$my_meta->addText('text_field_id',array('name'=> 'My Text '));
//textarea field
$my_meta->addTextarea('textarea_field_id',array('name'=> 'My Textarea '));

5) Finish Taxonomy Extra fields Deceleration [important!]

$my_meta->Finish();

6) Getting Saved data

$saved_data = get_tax_meta($term_id,'text_field_id');
echo $saved_data;
