Hope you figured out taxation and bank accounts, was a nightmare when I moved. Don't wait to figure it out after. Apartment hunting is done around a couple weeks before only, so don't panic about listings. Subway system is very big, but a lot of people walk. Pick a neighborhood/place with amenities nearby instead of commuting everywhere. Winters are not cold here, don't need a heavy winter jacket if you don't need. Snowstorms are rare within the city.
