SQL Server Reporting Services Integration Mode

We have installed the SharePoint WFE on the SQL Server Reporting Services Server but we want to limit the sharepoint services running on the box. We are assuming that Timer and Administration service should be running on that box and all the other services like "Web Application", Incoming Email should be stopped.

Is there an article available where i can find all the required services for sharepoint which should be running to support SQL Server Reporting Services Integration Mode

Thanks.
