It's been awhile since I've looked at the kits, but this seems like it would be a great deal for a starter kit.
Austin Homebrew Supply
Not sure what it would take to get that out to germany though.
I'd try looking for a local shop to you, to see if they have any starter kits, etc.. that's what I did and they were a lot of help with getting me started.

If not, Austin Homebrew supply (linked above) has been my go to online store.. they seem to have the best deals/ingredients.
The best thing you could do is get a book and start reading. I have this book:
Amazon.com: How to Brew: Everything You Need To Know To Brew Beer Right The First Time: Books: John J. Palmer
And it's been extremely helpful.
