This will be hard to describe. I'll try.

Treat it as a tiny proportional joystick, which it is. I use index finger of dominant hand. Press hard and it'll fly the cursor across the screen. Press gently and it'll give excellent precision. If you keep overshooting, you haven't adjusted to gently enough. It is less movement and more thought for pixel perfect precision as you can barely feel any feedback but still get movement.

I always have to turn up acceleration, but rarely sensitivity, in Trackpoint settings a notch or two for my own preference. For me, if I turn sensitivity down, it ruins it. YMMV.

I will left, right and middle click with thumbs as they're just below space and land there naturally.

Thumb on middle and drag to scroll at pressure sensitive speed for as long as you press. No need to "reset" when you reach the end of trackpad or finger on scrollwheel. Two thumbs and index finger means select and paste are almost as fast as vi-only approaches, as it's placed so you're essentially still typing. :)
