Hello Dragan.
Here is the script, that can help you.

I think, you can divide the comp with text or every word on some pieces,
then, animate one piece, and apply animation to others with a shift.
And apply other effects above on precomp.
You know, somewhere around is an Andrew Cramer's tutorial about positioning layer in depth by a script. I think you can apply it to those 3d rotation word at the end.
