According to the web site, the October scores will be sent via email on October 25th. I think that is the day that they are also processed and available for schools to view.
I am waiting until I get my score to send out the applications. In regards to the other question, I don't think it matters. I had them sent to me so I had it ahead of time. I was scared if it got sent to the school that my application may have not arrived and it would get lost in the shuffle, delaying the time by which my application is considered "complete."
