Systems that have trackpoints have physical mouse buttons, so you can just do real right clicks. Scrolling typically has its own input combo: hold the middle mouse button plus push the trackpoint to scroll in whatever direction you're pushing.

If there's a trackpad as well (usually there is), you can still do all the multi-finger gestures on it unless you choose to disable the trackpad altogether.

Fwiw, I don't find the trackpoint faster or more precise than the giant MacBook trackpads. Its main advantages are being closer to your index fingers' likely resting position on the keyboard, physical mouse buttons, and requiring less vertical space than a giant trackpad.
