Dumping Most Info From DB

I am finally ready to take my live site powered by vB and transition over to xF. I have everything configured and the test site is ready to go.... but I have run into a slight probem.

Unfortunately I did not follow Brogan's directions when I started:

The next step is the most important; using phpMyAdmin or similar, take a backup of the database.
This backup will then be the clean master database, which can be imported over and over again until you're ready to do the import for the final time.
The backup should be taken before you create any categories, forums, or test users, make any posts or add any content at all.
Now, I have a DB full of users, posts, forums, etc that I need to empty but I don't want to lose all of my addons, settings, phrases, style, etc. If I import again to get the latest data, I'm going to have lots of duplicates.

Any ideas for an idiot that can't follow directions?
