TFS Best Practices Project Hierarchy

Question

I've recently installed and started using TFS. Mainly using for source repository initially and then will get into using the Work Item features. I'm moving from using Vault as repository and have some questions on best practices for setting up the project structure.

My current structure from Vault is:
Projects
- CustomerName1
 -- Application1
 -- Application2
- CustomerName2
 -- Application1
 -- Application2

Can I have a smiliar structure in TFS? Is there any good documentation that has real examples and instructions on how to set this up? From what I see is all real basic and the books I have don't have real-life repository examples that mimic the structure I have.

I have created a new Team Project called CustomerName1, then added other Team Projects, Application1, underneath CustomerName1. However, I lose on the Application1 the separate folders like Work Items, Documents, Reports, and Builds.

So this doesn't appear set-up correctly.

Thanks ...
