Okay, I will try to help you out by using past experiance - I have a Shetland, he's about 8 and 9hh. When we got him, he would bolt from lunging, bite and kick at other horses, and lunging was a hassle.
First off, I am going to tell you you will have to be aggressive. There is a difference between mean and aggressive, you will have to be the later. This pony is dangerous and may hurt you if you are not.
That said, get your 'materials.' You will need -
The pony, a halter/lead, a crop, a lunging whip, a lunge rope.
I will start with the leading. Once you have caught your pony, come into a small space, like an arena, or preferably round pen. A small field does well too. If you have nothing but a large field, it will do. Get your crop, now, and put it in your hand. If needbe, desensitize him. Sesitizing will come next. Make your pony back up. Start by pulling the lead back. If he doesn't respond, start pulling on it in short bursts, harder and harder. If he still doesn't listen, pop him in the chest with the crop. Once he backs, release all presure and pet on him. Walk him a bit, stop, and repeat untill he is backing decently.
Okay. Once you have your pony backing, try this -
Walk next to your pony on a some-what slack lead. At random intervals, just stop. Don't pull or anything. Just stop. If he stops with you, with you at his shoulder or ahead (closer to the head,) praise. I doubt he will the first time :p. When he does just keep going, snap at the lead, and make him back untill you meet his shoulder. *Don't move your feet!* When he is by you, pet him.
Do this very often. If you see no improvement, let me know :)
Now for the biting and stuff. Again, carry your crop. The very second he goes for the Morgan take that crop and smack him on his shoulder, and make him back the length of a football field. Make your body language very assertive, and tell him very sternly, 'Back! Back! Back!'
I don't have the experiance to tell you how to deal with biting at people and with the ears. I'm sure I'm going to get tons of hate for how I got rid of the problem with Pumpernickle (My shetland with the same problems,) but really you need that respect to get rid of aggression in a pony/horse. If you need any clarifications, again, let me know :)
