Q) The object snaps are set to the middle button on the mouse. Can the snaps be set to Shift + Right button the way you can in AutoCAD?

A) You can use the Control + left mouse button to pop up the object snaps menu. There is also a very convenient floating toolbar at the bottom of the options menu that has all the snaps. For that matter there are many different floating toolbars that are available that will make your drawing experience a little easier.
