Don't breed!!!
My personal opinion -- your husband's reason for letting you have a dog "to stud him out" isn't a good reason at all. You'd be surprised how many people have told me to breed my dog. He has a full registration and could be bred, but he is too large (8 1/2 pounds).... Besides, I don't want to breed and and only wanted a pet. He's going to be neutered soon......
If you are seriously considering breeding a little Yorkie, you should have gone out and really carefully checked the little boy. He should be a good example (usually more expensive) of Yorkie standards, etc.
The fact that your papers were limited, means that he was probably sold as a "pet only" and not a dog that should be bred.
Also - let the breeders say more about this. But, I think a dog's temperment should be considered when breeding as well as its looks. The things that you mentioned about your little pup don't sound like breeding material to me....sick, bad teeth, unsocialized, aggressive, etc.
I would tell your husband "oops" and get your little guy neutered and work on helping him become the happy, healthy, little pet you want him to be.
Good luck!
