The idea of showing last post first and the rest in reverse chronological order has been tried and was a dismal failure. I will not be brought back so please don't bother asking for it. The vast majority of people hated it, including me so it ain't gonna happen.
As for taking you to the last page of a multi page post, unfortunately that can't be done as the software doesn't allow it so you will just have to click on the last page number as the page loads and that should take you to the last page without having to wait for the whole first page to load.
