Rather than try and take on board all the new features in 1.1, you would be much better off installing 1.0.4 now and making yourself familiar with all the various options.
You can even set everything up ready for the import, take a backup, and then keep testing the import, reloading the clean backup, etc.
Then once 1.1 is released it's just a case of upgrading and setting up the new features.
