tikz - reproducing tree / diagram from spreadsheet

How can I reproduce diagram from screenshots below using TikZ (in version with arrows or curly brackets)? I’ve tried creating tree in TikZ using split rectangle nodes, but I couldn’t add children to them in such way that arrow (or curly bracket) begins in specified nodepart. Some of nodes (nodeparts) can have more than one line (if it will be possible also itemize environment) and it should be possible to set different background color for each of them.
