Your keyboard needs the middle mouse button. You can hold this and use the touchpad to rotate the part. For the keyboard joystick, you still need the middle mouse button programmed somewhere.
In perspective settings (render), there are some advanced orientation options, most of which I find completely annoying.
You can control spin centers by using the default; turning off the default and clicking on a feature and dragging the mouse, or selecting an alternate spin center with the view dialog.
