Welcome to the forum and you do have your hands full with 2 new dogs.
Good thing you have crates because the older dog (and you all ) can use it for 'time outs' when it gets nuts. But management of the puppy's day BEFORE the crazy time will work even better. I feel a bit sorry for your Husky because puppy's just really do take more time and attention so your bonding with him just will have to take a bit of a back burner or you'll end up with an adult GSD that's a complete monster
Don't work too much on 'obedience' with your new puppy. What's most important (and will help with the end of the day crazy ) are things mentioned ---> Top Training Expectations for Puppies
