Happy New Year to you, too!
Straight to the questions:
1. Comparing the pictures attached I am not quite sure how do you want to manipulate the Foreground color of a TreeListViewRow. Basically you may do this through a style targeted at this element.
Will you please share with us a bit more info about what exactly you are trying to achieve?
2.As per your second requirement indeed it requires functionality (e.g. merging cells) which with the current version of RadTreeListView is not supported out-of-the-box. Furthermore you have to distinquish the indentation level between the rows (circled area in ExpectedResult.png). However the logic behind this indentation is internally handled and there is no easy way to manipulate it by your side.
I look forward to hearing from you!
