Hi Aimlessly, I would second Cadbury's - I used to import Fruit & Nut by the kilo until they changed the recipe and I decided I could live without it. The other thing it's quite difficult to get hold of in Austria IMO is decent biscuits; I remember filling up an entire (admittedly small) suitcase once with Fruit & Nut and chocolate hobnobs! And if your friend likes tea, I'm sure she'd appreciate a box of tea bags as they're very weak (and only available in packs of about 25) here.
Heinous I finally took your advice and had my first proper (i.e. at a Christmas market) Glühwein this evening! We did go to the market last weekend too, but I stuck to punch then for some reason. Definitely agree about Glühwein plus Plätzchen (had forgotten that word - they're just called Kekse here) being a balanced diet. 
ptumbi Glad you enjoyed Hamburg. "geil" is generally used to mean cool here nowadays by people much younger than me although it still has a bit of a risqué sound about it; our neighbour's 12 year old used geil the other day and then noticed I was there, so quickly apologised. Althoughit can't be all that bad as it's used in advertising slogans; one chain here claims that Geiz (stinginess) ist geil.
I have no idea what happens if you don't pay your TV licence, but we don't have cable or a satellite dish, so no Sky. But we do now have 13 channels as we bought a new TV on Black Friday - even if most of them seem to be regional variations of ORF1 and ORF2.
Ambling We're also thinking of trying the Netflix trial month; I just wish there was some way of finding out exactly what's on there beforehand (am sure there must be; I just haven't found out). Mind you, I suppose that's what the trial month is for.
Hello to Woolly, Nutella and anyone else lurking!
