Jesus Ino is such a wingwoman for these two xD but eventually something's going to slip through and she'll be doubting the entire thing. Just a matter of what. As for the juicy details, I think she'd go to Sakura more than Shikamaru, as the latter wasn't really willing to give her more than she needed to know. I think Ino's necessary for the two, but for obvious reasons she'll stick to Sakura more since she has a feminine eye and won't hold much back. 

I was young when I read the final book, and not much of a writer as I am now, but the final pairings made me question just what Rowling was thinking. I'd let them believe whatever they want, since it doesn't get in the way of what I believe and what I see. And what I see is, no way in hell did Hermione and Ron make an awesome match.
