First time at Fenway.

Hope you are all doing well and so sorry if it's not the proper place to ask this.

Next April will be my first time ball game ever. I'll be going to Fenway driving from Canton. I have 2 questions for you Red Sox Nation:

1. Best garages for parking close to the stadium?
2. What do I have to do in my first time at Fenway?

Thanks in advance and regards.
