As an aside, you also listed separately Numpy, SciPy, EPD, Ureka, and Anaconda.

First of all EPD no longer exists as such and now is called Canopy.  All of 
Canopy, Anaconda, and Ureka are standalone scientific Python *distributions*, 
each with their own copies of Python itself, Numpy, SciPy, and many other 
popular packages.  In principle they can all coexist on your system, though if 
you have to ask I'd recommend deciding which one best suits your needs and 
sticking with just the one.

As Tom said, if you need IRAF you should use Ureka, as it's the only scientific 
Python distribution developed specifically for the Astronomy community and that 
includes IRAF and Pyraf.  Full disclosure: I work for STScI which is the primary 
contributor to Ureka, but I don't personally have much connection to the project 
and don't use it personally.  I hear it works pretty well though.
