Use time outs - find one spot to use all the time. Set him down and keep setting him there until he stays put.

When I let my son out of a time out I ask him if he understands why he's had a time out. If he doesn't I explain it to him. Sometimes I allow him to come out of time out when he's ready to apologize to me or to do as I've asked him to do.

Don't allow him to choose his own place for time out, as that's still giving control over him that you need.

The other thing I do with my son is deny him toys and activities that he normally does during the day. If he throws a toy, at me or anywhere else, that toy goes up on the shelf for a day or maybe a half a day. If he's screaming I make him go to his room. He can bloody well scream his lungs out for all I care, so long as it's in another room. I won't fight with him. I'll just take his hand and walk him to his room, get down to eye-level with him, and tell him that he's welcome to come out whenever he is done screaming.

My son is no angel but he is otherwise a very good kid. For a while we had to use time outs quite a bit, now it's not even a weekly thing.

Good luck.
