I agree, specialization is the way to go (Paleobotany, archaeozoology, ceramic studies, conservation, DNA studies etc). If you have a knack for 'hard science', try getting some of that into your curriculum (physics, chemistry, physical geography), you'll beat the competition easily. If it's classical archaeology you're interested in, as opposed to ancient history, forget about ancient Greek and Latin, you won't need them. Italian, German and French is what you need to read 95% of the scientific output, probably in that order if it's Roman archaeology.
