I looked at your first thread about this and while you did get some really good advice, I think it might be important to back up a step and look at what your pup does when you first let him out of the crate. I am guessing, since I didn't see it mentioned, that he is probably really excited and runs out of the crate as fast as he can. If that is so, I'd start working on requiring him to be calm before you ever let him out.
It will require many repetitions and much patience from you. He has had 6 months to build up bad habits, so it may take a lot of patience and work on your part to train him to improve his manners.
I think you will find it much easier to get him to stop jumping on you and biting you, if he comes out of the crate calmly.
If you are getting him out after work or first thing in the morning when he hasn't seen you for hours and is really excited, I would use a very calm tone of voice, if you say much at all.
If you use an excited voice you will only make him more excited.
Start to open the crate only if he seems pretty calm. If he acts like he's going to blow out the door, shut it in his face. The intent isn't to slam it so hard that it hurts him, but bumping his nose may just make an impression. Wait until he is reasonably calm and try again. I would go ahead, if he is calm, and reach in and put his collar and leash on. That way you have more control once he is out of the crate.
Keep your treats handy. Anytime he gives you the calm behavior you want I would give him a treat and tell him in a very calm voice 'Good Boy'. No excitement or yelling if he screws up.
By having the collar and leash on, you have a lot more control. You can give him a correction, if necessary.
If he starts to jump up, tell him "Off" and give the leash a couple of downward snaps towards the floor.
You are helping him get back to the floor where he belongs. I know you said you do not mind him jumping up on you but that is excited behavior and if you allow it, it can lead to other unwanted rude behaviors.
For a very young puppy, like 8 weeks old, I wouldn't correct biting, I would redirect his biting to an appropriate toy. In your pup's case, I think he is old enough to be carefully corrected for biting. You said he went through "kindergarten" at 4 months old. Could the trainer from that class give you some pointers on stopping the biting? He is big enough to really do some damage without really meaning to!
