and for update checkboxes value

app/code/core/Mage/Adminhtml/Block/Widget/form.php

          else if ($inputType == 'checkbox') {
                    $customer11 = Mage::registry('current_customer');
                    if($customer11->getData($attribute->getAttributeCode()) == '1' || $customer11->getData($attribute->getAttributeCode()) != '')
                        $element->setChecked('1');
                    else if($customer11->getData($attribute->getAttributeCode()) == '0' || $customer11->getData($attribute->getAttributeCode()) == '')
                        $element->setChecked('0');
                }

set this codition in function _setFieldset in form.php file for showing your checkbox is checked or not in backend Account infomation page in magento.


            $emailprefs = array(
                'ATTRIBUTECODE1','ATTRIBUTECODE2','ATTRIBUTECODE3',...,
            );
            // Prepare customer saving data
            if (isset($data['account'])) {
                foreach($emailprefs as $pref){
                    $data['account'][$pref] = isset($data['account'][$pref]) ? 1 : 0;
                }
               
                if (isset($data['account']['email'])) {
                    $data['account']['email'] = trim($data['account']['email']);
                }
                $customer->addData($data['account']);
            }

Put this code in function saveAction() in CustomerController.php page for updating your checkboxes values in backend Account infomation page in magento. Replace 'ATTRIBUTECODE' with your checkboxes attribute codes.
