Start training from day one
Obviously she'll still be a baby both mentally and physically, so you can't expect instant potty training or anything, but you can start to teach her to pay attention to her name, etc.
If the other dog is fully vaccinated and is not visiting places like the dog park, I'd introduce them right off. I wouldn't bring a dog to a dog park until all 3 sets of shots, but you can start carrying her out to places to meet people at the regular park, around your neighborhood, at stores that allow dogs (like many camping/outdoor stores, hardware stores, farm stores etc).
And this is just my opinion, but I dislike dog parks as a means for socializing a puppy- there are too many poorly behaved dogs and you risk a scary or dangerous encounter that can really hurt the socializing process. Try socialize with friends' dogs that are well behaved and sign up for a puppy kindergarten class if one is available in your area.
