You get your student cards during enrolment day. They ask for your photograph, put it on some prepared paper and then laminate it. It's pretty crap. The only way to get a proper one is to 'lose' your current one and then apply for a replacement at Fisher Library at a cost of $15. During semester, there are usually SRC elections. Don't vote in them unless you want a big hole on your student card.
As for the iPOD business, from what I know of Apple dealers will give students a discount of 10% on the mp3 players.
