Cant speak specifics but there are numerous pre-order threads out there.

1. No one knows that yet, but we will know on Saturday at the live letter.
2. If you are buying from their online store you will usually get it the day it comes out, sometimes the next day. This of course is pending no problems with the shipping company (there are always those unknowns like weather and etc). Furthermore, the pre-orders come with early access which means they will be giving out codes before you actually get the game so missing days won't be an issue. (Usually they add a grace period of a few days after the early access ends before you have to have the real game)
