Less cryptically, that's Fowler's Modern English Usage.
NB that "Modern" was originally 1926. It's been revised a couple of times and I find it reasonably interesting, but although it probably is the nearest thing to an authoritative text, it's not really a coursebook. Might also be worth looking at the Guardian and the Economist style guides, which are quite good in identifying tricky situations and giving consistent answers.
In some ways, the best way of getting this stuff ingrained is simply to read lots of conventionally well-written text. Broadsheet newspapers, literary fiction, periodicals like the Economist or Spectator or Prospect or New Statesman, some (relatively few) long-form blogs (I quite like Jack of Kent, and Charlie Stross's one at antipope.org). Read lots, and the good stuff gets ingrained while poor and ungrammatical writing just begins to feel unnatural.
(The other issue, of course, is letting go of an obsession with grammatical pedantry. It only actually matters where it starts to interfere with understanding.)
