The carrier will try to give a small crosswind towards the island, so as to avoid massive rotor over the deck. However, that is determined by operational expediency.
When I was young and not overly bright (as opposed to now, where I'm older) I worked for a short while on a carrier - it took me a week of sitting through Harrier pre-flight briefings before I finally worked out why they never briefed QFE !
I don't recall an ILS, I think that they used some form of TACAN approach, but could be wrong - that wasn't my thing to worry about at the time.
