I would concur with LHurtado's comments re BAGD and LSJ.  I would add that one
can also profitably consult Louw and Nida, Greek-English Lexicon, 2 vols., pub
by UBS.  This lexicon represents something of a paradigm shift in that it sets
up "semantic domains" and then lists which words fit the domains.  Thus it is
oriented to semantic fields of various words rather than semantic range of a 
single word considered diachronically.  Vol 2 is the index of domains and words,Vol 2 is the lexicon proper.
