Yes mate, there is the drain plug under the diff. - which you describe, and another in the oil pan or sump, for which you have to remove the plastic gearbox undertray to get to. Have you run the car? If not, drain about a litre or so from this - there's a chance that this will be mostly old oil - as long as you haven't run the engine (which will churn and mix the oil) then top - up as normal.
