David's answer is largely correct, i.e., there is no need to install all those elements individually, simply use the latest version OpenStudio installer which will install OpenStudio and all the components you mention for you (excepting the SketchUp app). Since you explicitly call out Radiance in your list, I should point out that the OS installer will install Radiance, but it does not make all the necessary changes to your environment to use Radiance outside of the OpenStudio environment. If you plan to simply use the Radiance Daylight Measure that is on the BCL, then you would be fine.
