In addition to having, it turns out, an amazing generic CSV file import tool, Keepass and its little cousins are gorgeously well documented. It will never fully replace (the buggy) Quick Password for ease of use, but it has a future beyond iOS4 so I'll learn to love it. Here is all the documentation I needed to get started:
Getting Started Guide: https://keepass.info/extensions/v2/docs/KeePass2-GS.pdf
How to import from CSV files: https://keepass.info/help/base/importexport.html
Where to download the desktop app from: https://keepass.info/download.html
