I am actually pretty sure that Sam saw Carly at the end. If you look closely you will see Sam turn her head slightly after the kiss into Carly's direction and since Carly wasn't really hidden Sam must have seen her.

And I agree with you that Gibby was way more funny when he appeared only when they had a nice storyline for him, like in iQuit iCarly.
