Ok people, my main problem is that I was shocked how arrogant and rude I have been treated here.
I'm not stupid, I'm absolutely clear about it that my translations are probably not perfect, but as long as I can understand something from it I will keep on reading. (better then nothing).
And as I told before, if I were as far that I have learned more grammar till now I wouldn't ask. But I have started japanese only 1 semester before. But it seems that I have chosen the wrong forum for my questions. Even people with ask for stupid Kanji tattoos get more nice answers than me.

It became my favorite book, because it's a series of 12 novels: I could read 3 of it in german, 4 more in english, I'm about to read 3 more in spanish (this last one the same way with google and dictionaries - and my native speaker spanish friend checks it, but mostly she don't have much to correct it.)
Only 2 books weren't translated in any other european languages and I can give it only a try because I have a chinese version to compare it.
(No one of this languages are my mother tongue, not even german.) And I know the anime and manga versions, but the original novel is of course far better.
@Toritoribe: And thank you for your help, the answers for 3-5 were quite helpful, but your "hard core" grammar explanation for 2) was more than confusing for me.
For the example in the link: I don't understand what the person made wrong to (mis)understanding the sentence in question. I did not.
I not only put the texts in google and copy it as my translation, but I work with it and sometimes it takes half an hour for only 1 sentence to get a roughly meaning.
I don't estimate you to translate the whole book. I posted my own try as it is told in the "read before". It was only 5 sentences in question after reading more then 20 pages.
@lanthas: thank you for the story I'm not surprised about it. I think it's normal. A native speaker looked yesterday about my translation and said that it's a very good translation. @@ You can imagine, how surprised I was. (And I can still hardly believe it.)
