Ordering & Shipping: Either as usual from Amazon very quickly and easily (after Austria).
Registration of the product (for Student and Teacher Edition): As you get a very high discount as a student, I opted for the Education version. This one has to register on Adobe.com/de but only. When registering you had an Adobe Create account (if you have not yet), specify 2 code from the box and at least upload a proof of studies (png, jpg, pdf, ...). I've done this on Friday morning and was given the serial number on the next day by email.
The software itself: is very sophisticated and professional. So the transition from element to Creative Suite is difficult but possible. Help can also be found in [...] where you can free (!) Watch instructional videos.
All in all, the software, despite a price of around 600 (as of August 2012) highly recommended!
