It's important that the child still comes over to interact with you and your husband. However, with a pre teen, it's important when disciplining that you word it just right. Try to avoid telling him don't, no, you can't etc. Instead try:
"..by talking back to us, you are sending a clear message that you don't want to use the computer tonight..."
"..by cleaning your room, making your bed, and picking everything off the floor, you have told me that you really want to ride your bike."
Make it about him, he'll be turned about, but it works. I'm a teacher and I have little to no discipline issues with this technique.
Also, it's important, that when he's upset, don't try to reason with him, or discipline him, or touch him. This only builds up more adrenaline and will make him more aggressive, also when a child is this upset, all of his communication skills fail.
Always replace bad behavior with an appropriate behavior after he's calmed down. For example:
"It was clear that you were very upset because we turned off the TV, cursing and throwing things is not appropriate behavior, if you don't want to eat, you can say to us "hey, I'm not ready to eat, or you can retrieve to your room to read a bit, that's appropriate."
He's going through a hard T., and remember he's frontal lob is not fully developed yet.
