Answer 1

You have initialised $data twice. Once in the beginning of the function and again in else condition of upload.Inside else condition of upload change like this
$data['field_input_name'] = $w['file_name'];
It will work.

Answer 2

$data array's keys are converted into variables
$data['someKey'] = array(
'templateVersion' => 'template1',
'headerVersion' => 'header2',
'css' => '',
'navBarVersion' => 'navBar2',
'main_content' => 'myaccount/myAccount',
'page_title' => 'example.com - My Account',
'footerVersion' => 'footer2'
);
In view you can access as print_r($someKey);
use die(var_dump($someKeys)); in view to see results
As you are trying to upload images in CI you can use
echo $this->image_lib->display_errors(); for some other error detection or debugging
