For choosing a case, let aesthetics be your first priority (you do have to see it probably every day) then look for problems others have described in reviews, go from there.
Answers to questions
1) You'll get slightly better performance from the R9-290 (one tier higher according to Tom's here http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html ) so, if you want Watch Dogs, then sure. Shouldn't be a problem
2) I would expect 16GB of ram to be enough for what you're describing there
3) No, not a requirement. But I'll suggest the monitors be the same resolution, refresh rate and size for visual comfort
4) The Core i7 4790 is better (not by much but it is better)
