Specific Advice
I must say that some of the advice mentioned above should be taken with a grain of salt. As a German resident I would say that a lot of answers really depend on your specific needs.
Do you speak German?
If you do, you can save yourself a lot of hassle and money by improvising as soon as you get to Germany. If you do not, but are staying at a host family who will take care of you upon arriving, great - both is true; even better.
You should get yourself not an adaptor, but the 2-pin power chord extension that goes from your power brick into the wall (the europlug "Eurostecker") for greatest convenience. You can pick it up for a buck or two at any hardware store in Germany.
If you want to be safe, rather than sorry, and need your mac powered on arrival, by all means get an adaptor at the airport.
My one advice, if you take it, would be to get in touch with the people who you will be staying at ASAP. If you know the university you will be attending, get in touch with their student body or some exchange student organisation you might find on their home page. They will be able to sort out your specific needs. They will tell you, whether you will have free WiFi access at the place you are staying/the university and point you in the right direction.
Seeing as the "computer culture" is different from the US mostly in terms of costs/access points, you will need to figure out how to get your fix locally any way. Just like you probably are going to get a cell phone. Infrastructure is great, so no need to worry. Adjusting takes a couple of weeks - just don't buy a long term phone plan the first day that will cost you your first born to call home, but stay calm and you will soon be fine.
