You did the redirect right if you used 301 Permanent Redirects. However, the redirects need to point to the same content that was there before (eg. oldblog.com/2006/04/05 should not redirect to jimmyzimmerman.com/) otherwise it will appear to Google that you are duplicating content.

Also, if you register with Google Sitemaps and submit a sitemap to Google they will provide feedback on which URLs of yours are being indexed and which are returning errors.

Remember, any time your server returns a 404 to Google, they drop your page from their indexes.

You should also be redirecting http://www.jimmyzimmerman.com to jimmyzimmerman.com since the search engines (incl. Google) consider those two seperate sites.

Also do a search for your old site on google like “site:jimmysoldsite.com” and see whether any links come up broken.
