How exciting! I know you can't wait for his arrival! Enjoy this special time!!!
I will try to help out all I can. I am still a fairly new Yorkie Mom only having KS 4 months, but I will see if I can add any advice.
1. I am not sure on the first question. I have never had a boy. But my first thought too went to those belly band things. I have heard so many YT'ers rave about those.
2. I think a carrier would be nice for when you have to walk up/down the stairs too. I can imagine 2 would be a handful. I have this carrier that I received as a gift and I could easily fit 3 of Katie Scarlett in there, so it might work for you to put them both in one together just to go up and down the steps.

Or if you wanted them separate, what about a bag (like those Kwigy Bo's) to put Sophia in over your shoulder and then a smaller carrier you could tote for Brody?
3. I've never walked more than one dog, but all the dogs/owners we come across in the park that have 2 or more have those couplers and they look like they make life much easier.
4. Possibly feeding them in different rooms if they try to eat one anothers food? I know it may be tricky though with Sophia free feeding.
Sorry I wasn't too much help! But I do want to say Congratulations! I hope everything goes smooth for ya!
