It's a work-in-progress, mostly documenting stuff that I've needed to do.
Table of Contents as follows: (as of July 3rd, 2007)
Creating multiple Web Applications on the same port
Adding Forms Authentication
Changing Site Collection Administrator
WebDAV / Batch Uploading
Custom Columns (Document Properties)
Again, most of this stuff is built on a combination of trial and error and google searches. We've got some SharePoint 2007/Windows SharePoint Services v.3 books here, but honestly, I've found them to be a bit hard to read, especially when troubleshooting. Or looking for very basic steps.
