You're going to be okay. Try not to worry so much about doing everything "right"...most of that pack theory has been completely discredited in dog training, so don't sweat that alpha stuff.
I wouldn't worry about her manners right now as much as getting her around kids, babies, and other friendly dogs as much as you possibly can. The socialization window does close. Puppy class is great that way.
The rest you can catch up on when her brains arrive. If she's like Mr. G, that will be in about 24 months.
Sending you a hug.
