If you click on Preferences you can enter the username and password required for MySQL database access, as well as the database name (usually "eq" but I tend to number mine along the version, e.g. eq31).
Importing databases is used when upgrading from a database for an earlier version of the emu to a later one, at least theoretically. I find that it works in practice only for small to medium-size databases though. :( For example, you could import data from an "eq31" database to an "eq32" database and the tool will try to prevent duplicate records from forming as well as try to make sure that foreign keys are properly translated.
Generally speaking, importing is something that should be done *very rarely*. When setting up for the first time, all that you should have to do is connect to the database. There are some useful guides around the emulator's homepage and forums that describe how to set up an EQEmu database.
As I think about it I don't think I've added entries in the Preferences screen for importing the new db tables from 0.3.0 and up (not to self: do that for the next version). They are added in the Preferences screen and saved to the INI file; there is no coding involved. The screen describes tables, primary keys, and foreign keys that need to be remapped when importing. If you look at the tables list on the left portion of the screen it lists tables that will be imported.
