One additional suggestion: If you are going to work offline for an extended period (weeks to months), I strongly recommend making backups of your database periodically during that time to a memory stick or external drive. That way, if your drive fails or you have some other catastrophic failure, you don't lose ALL your work. And if everything goes smoothly and you get back to an internet connection without any hiccups, you can sync back to the cloud and throw away the backup.
