I was not able to see the error when I visited the page. If you are inserting the content part onto the page you must ensure that you have the includes at the top of the page and that they are going to the correct location. Is your CMS in a subfolder? If so you will need to prefix these paths with the subfolder to ensure that they link to the pages properly.
If the pages are linked in properly and the database is accessible you should see the content on the page.
Also, for setting the default value you can use any MySQL gui tool, you can instal phpmyadmin locally, you can use the MySQL Administrator tool that you can download from MySQL.com or you use any other third party tool out there that you like. I use SQLyog myself, it allows me to admin the MySQL as well as execute queries.
