My baby has those same issues! She paws for attention though. I'll be grooming her and she will be totally fine, but as soon as I walk away and give my attention to something else, she starts pawing! Like Kyani's horse, as soon as you look at her she stops and looks all innocent! She just started doing it so I ignore if for now, but we'll see.
As for the mouthyness...chances are he's teething or curious. Like spirithorse said don't punish him, just don't let it get out of hand :)
