- is there any chance to hide or delete the auto-directory
If by "auto-directory" you mean Table of Contents, the answer is no, you can not delete it and create you own.
is there any chance to link to a word that is NOT part of the body text
Yes. A single word can act as a link. But not as a link fromyour own ToC.
@1 - frustrating (see headline); if I would only understand these silly restrictions ....
@1+ - why is a galery-image restricted to an minumum width of 279px ...
@2 - whenever I try, add-Bookmark "+" is grayed out, no matter, if "placeholder" (menue: format/extended) is activeted or not.
I'm on a page/
page is formatted by a template-page/
I add a textbox/overwrite it with, say, "Situation in 1999"/
I highlight/activate the term
+ remains grey.

Step back, take a breath. iBooks Author is narrowly designed. It is not intended to be an all purpose design and publish application, suitable for all people in all situations. What that means is, a gap exists between what we envision and what iBooks Author can do. This forum is filled with questions from smart, hard-working writers, publishers, designers, and computer programmers who begin with "Why..." and end in "...the way I want?"
A Tableof Contents with 40 chapters is not a nightmare.
To gain some perspective on what this program is and what it does, I suggest reading this book, it's free: Publishing With iBooks Author, from O'Reilly press.
I shall ponder #2 above...
This is how I solved "the problem"
I created my own table of content WITHIN the Chapter "preface"
As you see: each Chapter ha a picture and a headline (red arrow). IN FRONT of the headline (that you see) is a second headline (with opacity set to 0), that is activated as a hyperlink to the first words of the respective chapter. So tapping on the headline brings you to the chapter.
AND on every page in the book is an "i"-Button that brings you back to the ToC.
So, the auto-directory is still there (as a second navgation tool), but the user may and shall use my ToC instead.
