Answer 1

load config product:

   $currentProduct = Mage::getModel('catalog/product_type_configurable')->setProduct($this->getProduct());;

    $products = array();

        $skipSaleableCheck = Mage::helper('catalog/product')->getSkipSaleableCheck();

getting all all simple products

    $allProducts = $conf->getTypeInstance(true)
            ->getUsedProducts(null, $conf);

    foreach ($allProducts as $product) {
        $products[] =  $product;
    }
        getting all configurable attribute of that products
        $AllowAttributes=$conf->getTypeInstance(true)
            ->getConfigurableAttributes($conf);

Getting config attribute for this product by attribute value id and label

    foreach ($products as $product) {
       foreach ($AllowAttributes as $attribute) {

            $productAttribute   = $attribute->getProductAttribute();
            $productAttributeId = $productAttribute->getId();
            $attributeValue     = $product->getData($productAttribute->getAttributeCode());
            /* Simple Product data */

            /* getting option text value */
            if ($productAttribute->usesSource()) {
                 $MYabel = $productAttribute->getSource()->getOptionText($attributeValue );
            }else{
                 $MYabel='';
            }


        }
    }
