regarding the "got": When I started to learn (British) English at school 35 years ago, we had school books that were then 10 years old or even older (i.e. from the 70s). We learnt to express possession of something as "I've got a book." , "I've got a pencil." and so on. Later on, when I talke to native speakers I learnt that hardly anyone uses this. But I always assumed that it use to be standard at one point - at least in the UK. Also, we learnt the use of "whom" as a relative pronoun (which is easy to understand for a German, by the way). But again, nowadays, nobody hardly ever uses this.
