Answer 1

Try this solution

        foreach (array('size', 'color') as $attributeCode) {
            $usedProductAttributesIds[] = Mage::getModel('eav/entity_attribute')->loadByCode(Mage_Catalog_Model_Product::ENTITY, $attributeCode)->getId();
        }

        $configProduct->getTypeInstance()->setUsedProductAttributeIds($usedProductAttributesIds);
        $configurableAttributesData = $configProduct->getTypeInstance()->getConfigurableAttributesAsArray();

        $configProduct->setCanSaveConfigurableAttributes(true);
        $configProduct->setConfigurableAttributesData($configurableAttributesData);
