Moving a blog out of my MU install, to it's own single install of WP

Currently, I'm using WPMU 3.1.2 and domain mapping to power a few blogs.

Now, I need to be able to move two of the blogs that I created within the MU install, to their own installation of single WP 3.1.2.

I have already exported the content, but I'd like to be able to transfer over the active theme and plugins (including their settings).

I understand that I'll need to somehow address the issue of DNS and domain mapping, too.

Your help will be greatly appreciated!

Thanks -
