Under Tools > Importer, there's a built in option for MT. *thumbs up*

Also, if you want documentation on anything, googling "wordpress $term" will generally get you the codex page for that thing in the first five hits.

There's decent directions for a lot of stuff in there, including things like set-up and theme modification. Wiki documentation pretty much rocks my world.
