In your case, you registered in two classes and one of them included "On-line journals, namely, blogs featuring self-help, personal growth, and gratitude." So, you'll have a good basis to stop a blog that offers information or commentary under a confusingly similar name. That is, if you went to court, you would have a good chance of prevailing.
However, you will have difficulty asserting your rights against the blogger under international cybersquatting rules, even if the blogger acted in bad faith, since all Blogspot.com blogs are subdomains. In other words, bloggers at Blogspot.com don't "own" domains; they've acquired limited rights to post under Blogger's (that's the company that runs the service) terms of service. However, if the blog's name is misleading or confusing people as to its source, you may be able to appeal to Blogger (owned by Google, Inc., btw) based on a violation of its blog content rules. Write to them and explain the situation; they may be able to help you out.
The Dear Rich staff admires your diligence in acquiring all these forms of protection, but the staff is confused about your statement that you have acquired copyright protection in the name, since copyright does not extend to names.
