As for the face to face with the co-worker, I'd go neutral but firm. I've had annoying coworkers in the past who, when confronted, seemed genuinely perplexed they were being perceived that way, good long talk about it cleared the air. On the flip side, I have a young coworker right now who is rude and annoying and is very content being that way. Our conversation about the way she interacts with me only served to scare her so now she stays away from me and doesn't interact. Win win!
I would definitely try speaking with her in private first about your concerns…she may have no idea how she is coming across and it is always more constructive to address these kinds of issues directly with the person involved before bringing it to the boss etc. Give her the chance to fix things before you report it to anyone else and potentially get her into trouble for something she may not even realize is a problem.
