If you go down the board to Teachcinci(?) post, there is a thread about the first week of school. Some of the ideas might give you some direction.
You are right, you probably won't get thru all of it. I never do! But it is better to have too much thannot enough. I read back to school stories, do introductions, a craft to go with the book, and go over routines and what we will do this year. What you don't finish, you do another day. There's no right or wrong to it, just do what feels right to you.
