If you're on Windows, you can get binary packages from the PyQt4 download page that will install everything except Python and Eric.
Ignore the source packages at the top of the page - scroll down to where the Windows exe installers are and make sure you pick the right one for the version of Python you want to use (2.7 or 3.4) and the platform you're on (32bit or 64bit).
You don't need any of those other downloads. Since you already seem to have Python installed, all you need to do is run the PyQt4 installer, and then run the Eric installer.
There is also a PyQt Wiki which you might find helpful if you're just getting started.
