Here're my 2 questions:
1) Does user interacts first with a view or controller?
2) Does model sends output directly to view or via Controller?

There are as many different interpretations of MVC architecture as there are programmers so there is no right answer here. Having said that I would rely more on the U. of Virginia than on some random one-man-band developer's blog.

To give this random one-man-band developer's thoughts:
Q1
In a Web 1.0 app (which is what is pictured in the second picture) there is no direct interaction between the user and the view, everything goes through the controller.
In a locally installed app, or in a Web 2.0 app, there may be direct interaction between the user and the view.

Q2
How data gets from the model to the view is not important, what is important in MVC is that a view must not be able to change state in a model. If the view does interact directly with the model then this becomes MVVM (model-view-viewmodel) rather than MVC.
