@roguecoyote I'm going to try to address each item separately...
Biting: I usually address this problem with (Xylitol free) peanut butter. Take a very small amount (because your pup is so young) and spread it on the palm of your hand. Offer it to your pup and give them lots of praise for licking the smeared peanut butter off your hand. If biting begins, close your hand and say, "no bite" (or just "no"). When biting stops, the peanut butter licking can resume. Once or twice and the problem should be resolved.
Pink Paw Pads: It's cold out and there is a lot of salt and chemicals spread due to the snow and ice. Even if your pup is just in the backyard, you can still help protect their paws. Just rub a small amount of petroleum jelly on the paw pads. It provides a layer of protection for your pups paws. Not a lot, but a little is better than none.
Tug of War: In my opinion, it would be better to teach Rogue to "drop" the ball when she brings it back. There are going to be times when you want her to drop whatever is in her mouth. Like when she finds food in the bushes on a walk. Being able to say, "drop it", and actually have her spit out whatever she picked up could actually keep her from getting sick. Ideally, you want Rogue to eat what you give her because you will know that it's good for her. If you enjoy playing "tug", do it on another occasion. Keep "fetch" as a lesson in coming back and surrendering whatever she has in her mouth.
Overall: I think you are off to a good start. You ask really thoughtful questions about Rogue and her needs. You are giving her lots of love and attention. And you don't seem to be frustrated or annoyed with any of the puppy behavior. You and Rogue (and your Mom) are all lucky to have each other!
