What Bully said, and you may also have to trim the trailing end of the front bumper as well.
Don't forget that if you go for a body lift then you maybe looking at altering things like the gear leavers, radiator mountings, fuel filler, steering shaft........
You may only need to fit a double cardan front propshaft if you correct the front caster angle using corrected radius arms, as these change the angle of the whole front axle and cause vibration/pulsing in the front propshaft. If, with a +2" lift, you find that the steering is very light, wanders all over the road and is hard to keep in a straight line then you need to correct the caster angle. If it's not like this then you should be OK with the standard front prop.
To give you an idea: I have a 300 TDi with a 1.44:1 Defender transfer box (brings the overall High Range gearing back to about normal), standard diffs, a +3" lift, caster corrected radius arms, TD5 front prop, +2" bumpstops, running 33x12.5x 15 tyres with wheel spacers fitted and fender flares to cope with the tyres on articulation.
