How can I add my "Custom Post Field" to the theme? In particular, the file "content_post.php" to see them appear in the list of posts under the category?
we are not sure what you exactly ask for but we think that we don`t have anything like that included into theme. In case, please take a look at http://codex.wordpress.org/Custom_Fields and check if this is what you mean because this article may help you.
