I’ve been fiddling around and trying to port 2 seperate blogs (the real online one and the testing one on my laptop) just by importing the posts. Something I’ve noticed with the back end of WP is the inability to manage which categories posts are under for multiple posts, you can change them one by one but not en-masse.

I’ll have to take a look for a plugin that provides this functionality or suggest this for inclusion in the next version of WP.
