I want to know please if Reporting Services can be installed and used with SQL Server 2008 R2 Express? I read that I needed SQL Server 2008 R2 Express with Advanced Services. How do I tell whether I have that or not? It's been a long time since I installed SQL Server. Thanks.

Yes, you need SQL Server 2008 R2 Express with Advanced Services to get Reporting Services. You can check Reporting Services Configuration Manager and try connecting to the instance to see if you have it or not. In case you are looking to install it, you can download it form here - http://www.microsoft.com/download/en/details.aspx?id=25174
