Great guide — one thing I'd add from my own experience with BIOS setup: always dump the BIOS from your own PS2 console rather than grabbing random files off the internet, since that keeps everything legal and avoids broken or mismatched dumps. I keep one single BIOS folder that both PCSX2 and LaunchBox point to instead of duplicating files across folders, and I make sure the BIOS region matches the region of the games I'm launching. This page was a handy reference when I was sorting out my dumping setup: <Link Removed>

One thing that catches people on the PC setup step is that the BIOS you pick in PCSX2's first-time wizard has to match your games' region — a mismatched region BIOS can make games fail to boot even after everything imports fine. Also make sure PCSX2's BIOS directory is pointed at the folder with your dumped BIOS files before running the wizard. I found this guide to BIOS setup for PCSX2 helpful for the dumping and configuration steps — it's strictly a setup and troubleshooting resource, and BIOS files themselves still have to be dumped from your own console.
