Trouble making site live

[Mad Jack]

Hello, my site is located at http://www.muddguitars.com/wordpress/. When I was coding the site I put it into a sub directory called 'wordpress' so that my old website could still be live while I was working on the new site. I want to make my site live now but I'm having trouble figuring it out.

I moved all of the files wordpress files from the sub directory into the root directory, but it just gives me a lot of error messages when it tries to load. I moved all of the files back into the wordpress sub directory, edited the index.php file line to read './wordpress/wp-blog-header.php' and left the index.php in the root directory. The site front page loaded correctly and I thought I'd cracked it, but none of the pages or links worked.

How do I make my site live?

Thanks,
Jack.
