Welcome to YT
You have great questions and I can try to help you with a few. We have a ton of information in the different forums you can browse through too.
1. Food is always a tricky question since there isn't a right answer for everyone. I personally feel Wellness to my 2 and that's because it works for my little guy with a super sensitive tummy.
2. Are you planning on crate training her? If so I would start her out in that right away. Sounds like you are all set with the blankets
3. Chew toys! Lots of them
I still remember those razor sharp puppy teeth~
4. I keep mine short too and only bathe them about every 2 weeks (more if they are rolling around in gross stuff, which happens). I don't blow dry because they hate it but if you start her out early getting used to it I bet it will be a breeze.
Good Luck to you and your new baby~
