First I will tell you that the rubbing is her way of putting her scent all over you. This is something all cats do, even kittens. The meowing could be her way of letting you know she wants to be close to you or it could mean you have not given her enough attention. Cats, especially kittens, need lots of love and a great deal of play time. As for the licking and nibbling, many cats do that. I have one that is ten and still sucks on my little finger. Some say it means the cat was taken from mom too soon, but I disagree. I believe it is just something some cats like to do.
