IIS Resource Kit
This has been out for a while, but worth noting.
IIS 6.0 Resource Kit: http://www.microsoft.com/downloads/details.aspx?FamilyID=80a1b6e6-829e-49b7-8c02-333d9c148e69&DisplayLang=en
This is mainly the documentation portion of the Resource Kit. It's got LOTS of great information about managing and securing your IIS Servers. It's a lot to go through, so mostly it's a reference guide or something to poke around in as you get curious on certian areas.

This includes about 14 handy tools for IIS 6, but the ones that I think are the best are:
- Log Parser
- Metabase Explorer
- RemapURL
- IIS 6.0 Migration Tool 1.0 (Version 1.1 is now available via a seperate download: http://www.microsoft.com/downloads/details.aspx?FamilyID=2aefc3e4-ce97-4f25-ace6-127f933a6cd2&displaylang=en)
