New Rider - Need advice for maintenance and care

Hey y'all! I am buying a 22 MT03 next week as my first bike and I'm so excited! I don't have a ton of experience, but I want to be prepared and treat it is well as I can so I have a couple questions.

What is the maintenance that I should be doing regularly and annually?

Type of gas to use?

Heard the stock tires aren't that good, should I replace them and with what type of tire?

Are there any problems I should look out for?

I live in the Northeast and plan to store it in a basement during winter, any tips/process for winterizing it?

Any tools I should buy now to work on it with?

Any other tips would be appreciated!
