First Take your index.php file and open up a text editor add blog just the way I did below:
require('./blog/wp-blog-header.php');
Then Copy this file back inside the blog folder but also one level above outside the folder so you'll see folder named blog and index.php side by side
So now on the settings-->general-->
wordpress address is showing: http://www.erichschuler.com/blog
site url is showing: http://www.erichschuler.com/blog
If that's correct in this area you should then just be able to remove the four letter in blog from the Site URL Only click save and voila. now your site will point to just your name
If you're still concerned check out the book dig into WP is a great source and helped me a lot when I was getting started a few years back.
