Training and socialization will help with this. I second the "plant" idea. You should pick people you know will listen to you to help train. After they are well trained enough, they will listen even if the human isn't obeying the normal "calm" rules. You just have to start out slow and then start adding distractions until they get it. For instance, Rylie sucked at laying down and not moving until I released her... now I can jump around like a freak and scream and she doesn't move until I give her the command. I worked up the distraction level slowly.
Note: I would not recommend having a bunch of people/dogs over or taking your pup outside until the little one completes their shots. You should not take them out to pet stores or outside, etc. as they can get sick. In addition, most puppy classes will not let you join unless the pups are fully vaccinated. If they do, I would not take your pup to that class.
I let people over my house to see Rylie after she adjusted (I gave her a week, you don't want to bombard them after such a big life change IMO). However, I made them remove their shoes so that they didn't traipse in any kind of germs/disease from outside or anything. People can bring in dog illness. I also made them all wash their hands before they saw her. Rylie was 12 (almost 13 weeks), I would be even more careful with a younger pup. JMO. Once she completed her shots though and the vet okayed it, we were outside right away!
