Classification is a very broad term which simply means putting things in classes. Humans seem unable to resist the urge to classify. It's one of the most basic activities of any science, because it's easier to think about a few groups of things than about lots of separate things.
Taxonomy means giving names to things. It tends to go hand in hand with classification, but need not.
Phylogeny is the ``tree of life'' - the hierarchical structure by which every life-form is related to every other life-form.
Systematics is the process of trying to classify organisms according to their phylogeny.
Cladistics, also known as phylogenetic systematics, is a relatively new way of doing systematics. It works by analysing different taxa to find objective similarities and differences between them, and using those similarities and differences to derive a hierarchical structure showing which taxa are most similar to others. The assumption is that similar taxa are similar because they are related, so that the trees produced by cladistic analysis are approximations to the phylogeny of the group being studied. The cladistic method was first described in 1966 by Hennig, but has really taken off on the last decade due to the availability of cheap, powerful computers to run the analyses.
