Mr. B's having some of his manhood removed today, so we won't be able to make it to Petco for the puppy play group this Saturday :(

But to answer your question, our vet told us that it would be safe to have puppies around other dogs once they've had all their shots, including rabies. We had to wait till Mr. Belvedere was more than 12 weeks old before we had him around new dogs since they had to give him his shots in stages that spanned over several weeks. It's fine if Zeke wants to play with other dogs that you guys know (who are caught up on all their shots), but I'd avoid any dog parks, dog beaches or actually to be completely safe... anywhere where other dogs have been. Some dog diseases (like Parvo) are highly contagious and is shed in the feces of infected dogs, but even after the feces has been removed, the virus can live for months in the soil/area. Parvo can be deadly, so I'd also keep Zeke off the ground (sidewalk/street/grass) if you think other dogs have been in the area. A puppy's immune system is still really weak at 8 weeks, so it's better to be safe than sorry...
