Question : Citrix Design

I am looking for some advice on a citrix design for our environment.  We have 5 HP quad processor blades 12 GB of RAM in each blade we will be Virtualizing the environment w/ wmware.  We will be piloting for about 150 users.  I have never designed a citrix environment before and am hoping for some advice on the design.  What are citrix's best practices.  We have various applications that we will be publishing.  I need some advice on the data store(SQL Server 2000)  the data collector secure access gateway.  Are there any diagrams out there that show a detailed design.  Thank you
