We're working on a revamped installer for the next big release which will clear up a ton of this confusion. Until then:
* If you don't have Alpha User Points installed (sounds like this is the case), don't worry about that zip file
* If you don't have any of those other profile_plugins installed, don't worry about them (JomSocial, Kunena, etc)
The social_modules, install the ones you want to use. You can see an example list of each of them on the page below:

Hope that helps explain, but obviously, if you have other questions, just let us know!
