[Koha] Getting Data into Koha

Hello everyone, I a have been testing the VMWare Koha appliance, thank you Kyle!! Is there a fast way to get my isbn data into koha and then have it query a few Z39.50 servers to download the rest of the book data? We have about 2000 books. I can scan the isbn numbers into a text file and then import these into the mysql database. I also know how to manually query Z39.50 within Koha but that is a very cumbersome procedure. There must be an easier way... Any help would be greatly appreciated!
