1. Add the 14 hive's (or 12 hive's) bin folder to your server's PATH variable
2. Install the Sysinternals Tools, Network Monitor, and both the IIS resource kit and troubleshooting toolkit, so you don't have to do it when a problem arises
3. Follow lowest privilege as much as possible
4. Update to latest version possible, preferably by using a slipstreamed build, which should be retained for DR purposes.
