For the ground work...I also agree....I use the word QUIT. For the pawing, well....that's one that many people spend too much time fussing over getting a horse to stop. If it does bother you that much, take your foot and bump the leg that is NOT pawing from the back...up close to the back of the knee. Kind of like when someone comes up behind you and does it to you as a joke, so you knee gives a little....know what I mean? The horse will be surprised because the other knee gives and they will put the pawing foot down to compensate. Hard to explain here. As for the mouthiness, sometimes a real quick "elbow" works, then go about your business. It's the element of immediate surprise that works.
Just my two cents on the pawing thing...many people (myself included) see it as a sign of impatience and disrespect. My gelding did it for the first time ever the other day and he got a smack on the shoulder (not hard...more like a tap to get his attention) and a "Quit it!" in a stern voice. He already knows that phrase from being reprimanded for biting and trying to kick me while I clean his feet (he was an unhandled 2yo stud colt when I bought him less than a year ago), so he immediately knew that whatever action he was doing at that time was inappropriate and stopped. He got a "Thank you!" once he stopped.
However, I do agree that going back to basics (aka-ground work) is essential here, but I think for a reason not yet mentioned (at least I didn't seen where anyone had mentioned it). If your horse doesn't respect you on the ground, he isn't going to respect you in the saddle. I learned this when I retrained my old gelding from the ground up (had a VERY similar situation to yours with him) and it was completely reinforced to me with my current gelding. I have my gelding's respect on the ground. What I say, goes. So, when I get in the saddle, that respect transfers and what I say, goes.
