Answer 1

Here you can find an example of such tree. Article is not big so I propose you to read all 3 parts. Using such (level -> margin) converter with TreeView class seems to be simplest way to do what you want.

Answer 4

ListView        TreeView
|------|           |-----------|
Item1            + Group1                         Row1
Item2            -  Group2                         Row2
Item3                    X                              ......
Item4                    Y

The Composite Pattern Data Structure which holds the hirarchical Data for the TreeView controls the ListView. I synchronized the Hights of each Row between the two DataContents. it was not easy, but this way I can use all the rich functionallity of the Tree- and listView instead of implementing it from scratch on my on.
The Final Layout is sort of a advanced C# editor with Linenumbers (ListView).
