If your mind is set on allowing a litter..if there is a litter..then simply read all the threads regarding whelping...develop a close relationship with your vet and hope for the best.
Your female is 17 months..not too young IMO, the pups would be born when she is nearly 19 months...but that would depend on her size and pelvic structure...we all differ on these things, but most show breeders I know breed in the 16 to 18 month range...
IMO the best you can do for this Yorkie is to spay her now.
