So you want to perform your capitalization function on the post text? In that case you could use the postbit_display_complete hook and work on $post['message']. You could set a new variable then edit the appropriate templates and change where it's using $post[message] (postbit or postbit_legacy), or you could just change $post[message].

Edit: oh, I realized after posting that that you probably want to do it to the post titles and not the entire post text? In that case I believe it's $post[title] you want to change.
