These are from the blas-3.0 and lapack-3.0 RPMs which come with FC2. 
They are incomplete and probably not optimized, and the only thing on
FC2 which should depend on them is octave.  I'd think you can safely
delete them (sudo rpm -e blas lapack).

The default is in brackets, and is what you get if you just hit Enter
here.  It will work.

Yes you could, and the steps  you listed are not needed.  Though it
perhaps isn't clear, just create a subdirectory /usr/local/lib/atlas and
unpack one of the precompiled ATLAS binaries into it.  SciPy should work
fine with this arrangement.
