Confused about system requirements...

Hi,
I'm moving from WinXP to Vista and need some confirmation on the system requirements for using TorqueX, GameBuilderX and the Platformer Kit.

As far as I can tell I can do development on Vista and the software stack looks like this:
- Visual Studio 2005 C# Express with service pack 1 for Vista
- XNA Game Studio Express version 1
- TorqueX
- Game Builder for TorqueX
- Platformer kit


I cannot use:
- Visual Studio 2005 Professional
- XNA Game Studio Express version 2


Is this correct?

Does it matter if I have Visual Studio 2005 Professional and XNA Game Studio Express version 2 installed in addition to the required software?


Thanks,
Ty
