That blog is functional http://lifeafterbodilydeath.wordpress.com/ and as you have no content in http://rickyspracticeblog1.wordpress.com/ I'm not clear on exactly what you are trying to achieve.
You can, of course, make the first blog private and use it for testing and backup purposes. http://en.support.wordpress.com/settings/privacy-settings/
And, you can link your username to the new "primary blog".
Dashboard -> Users -> Personal Settings -> then scroll down to Account Details. Then scroll down to where it says ‘Primary Blog‘ select the URL for your primary wordpress.com blog and then save changes.
Now every time you sign into the forum we can all click on your username and your blog will be linked to it. And every time you leave a comment on a blog your username can be likewise clicked and your blog can be instantly located.
