Can you? I'm looking to build the Sharepoint Visual Web Parts.
I downloaded C# express and Web Developer Express but neither have the templates that all of the walkthroughs start from.
Is there any way I can get the template or do I HAVE to get the professional version.
Do you mean Web parts or Visual Web Parts? You can build Web Parts, which are really hosted in the ASP.NET namespace and not SharePoint with express. The downside is you need to build your control tree via code. It's not as easy as the Visual Web Part that is part of VS 2010.

Not sure if the WSP Builder templates are part of VS express, but that would make creating the deployment package easier.
This is an interesting discussion thread for your questions
I have no tried VS 2010 EXpress, but it seems you will need SP2010 for development on VS 2010.
So, you need to figure out to install WSPBuilder on VS 2010 Express
