Thank you for the question.
For the different views in the right part of your application you can use different RadPanels to contain your controls. Depending on the selection in the RadPageView, you just need to call the BringToFront method of the RadPanel that should be shown.
As to RadRibbonBar, on the SelectedPageChanged event you have to add (insert) and remove the approriate RibbonBar tabs
These approaches are demonstrated in the attached sample project.
I am not sure that I understand your questions about the norms. Generally, each specification is individual and it depends on you and your scenario how many RadPanels you will place on the right side of the applicaiton.
I hope this helps. If you have additional questions, feel free to write back.
All the best,
the Telerik team
