Yes they are plug and play, I went from non-projectors to projectors, as you said cornering lights don't work.
The dipped main is a H1 bulb (in the projector) I think the rest are the same (sorry been ages), but I would just buy new bulbs all round, best time to do so!
I actually went for LED H1 in the dipped main recently for better light, I also have LED side bulbs (501 W5W) and silver indicators (they flash orange, but look silver, so you don't get the "egg yolk" look).
