On post order I'm seeing 23 Oct, 23 Oct, 17 Oct. It appears in order to me. Go to settings > general and make sure your offset from GMT/UTC is set correctly for your time zone. If you changed it between posts, that can mess up the order. You can change the order by changing the published date as explained here: http://en.support.wordpress.com/posts/schedule-a-post/ .
At the top of settings > reading, you will see a section labeled "Front page displays." If you are looking to set a different page as a static landing page for your blog, you do it in that section. You have to create and publish that new page before you can choose it from the "front page" pulldown: http://en.support.wordpress.com/pages/front-page/ .
