Money
The currency in Berlin is the Euro, and currency exchanges can be found easily around the city. There is an American Express on Friedrichstrasse, a Reisebank in Hardenbergplatz, and a Thomas Cook/Travelex on Ostbahnhof. With regard to using credit or debit cards, you will find that Berlin, indeed most of Germany, is largely cash based - you can use cards, but you will find it a rarity rather than an expected method of payment. Berlin is generally a cheap place to both live and visit - rent prices are cheap, living costs aren't extortionate and it has the distinct feel of a place that is developing by the day - leading to the mayor defining the city as 'Poor, but sexy'!
Language
The language spoken in Berlin is German. Generally English is spoken widely and if you can't speak German you should be able to get by. There is a large Turkish contingent in Berlin; in fact, the city is quite the melting pot of cultures, languages and even religions.
