Good start!

Good start and the most important pieces are there! It’d be much better if tags & categories were imported – and media import would be a bonus!

Looks like tags & categories may have worked prior to 3.5, but WP code changed some of that making this plugin out of date if you want anything more than just the posts and pages themselves.

On the plus side, the code is readable and in OK shape, so modifications for the enterprising codemonkey shouldn’t be to hard.
