Answer 1

The object you want to access has the type WC_Order_Item_Product. Use its public methods to query it for data or tell it to do something.
This is how OOP works. You don't even need to know how the object properties are named.

Answer 2

I guess
global $post;
echo '<pre>';
print_r($post->data);
echo '</pre>';
echo $post->data->order_id;
