Yes, they mean notice period, and I doubt that they require a copy of your current contract (that would be EXTREMELY unusual).
Forget the Longe Range thing, that is only applicable if you hold a German ICAO (NOT JAA) licence.
By the way, pay seems to be rubbish: As a F/O on a 604 (1000h, non-rated) you will earn some 2.100 EUR after taxes and social insurances + 600 EUR in per diem.
