I agree with Lajocar. Even if you aren't going to blog much in the beginning, might as well set it up for the long-run. Plus if you host your blog on WordPress' servers you can't use AdSense because they don't support Javascript. If you do decide to do what Lajocar said, use
www.hostgator.com (if your host doesn't use cpanel). They have cpanel, awesome support and setting up your blog is quick and easy.
