The Practical Guide chapter (above) is probably your best bet for getting started. Other than that, you might check out the method sections of commonly cited papers by Fazio as well as John Bargh, John "Jack" Dovidio, Tony Greenwald, Mahzarin Banaji, and others. If you want to get really deep into it you might also check out papers by Roger Ratcliff. If other are reading this, feel free to add your suggestions to this thread.
