I mentioned before how PluralSight is creating a series of screencasts on the basics of WCF:
Aaron Skonnard has now created a second WCF Screencast showing you how to use the WCF Service Configuration Editor to add and modify WCF Service endpoints. You can watch the WCF Screencast here.
Don't forget you can also use the Web Service Software Factory from Microsoft Patterns & Practices to create WCF Services.
For WCF Security Guidance, check out the WCF Security Guide v1 Released - Microsoft Patterns & Practices WCF Security Guidance Project.
