I think it might be wise to stick something into the beginning that clarifies that the telegram is intended to help them get settled in TWP. Otherwise, it reads to me like a bunch of things that I'm not sure what to do with, and if I were a new player that might overwhelm me.
My suggestion for the beginning would be as follows. I've also added a few other suggestions, but take them as you will.
