1. The 3.0 Frameworks includes 2.0, so if you select 2.0 as a pre-requisite and you go to install on a machine that has 3.0, the bootstrapper will detect that 2.0 is already installed and will not try to re-install it.
2. Your 2.0 compiled application will run as expected on the 3.0 .NET Frameworks.
3. We don't currently have a .NET Frameworks redist bootstrapper package. You could create one once the .NET Frameworks redist is release using Bootstrapper Manifest Generator. Otherwise, look for the next release of Visual Studio.
