Starlight focusers are greaseless, right? They never require re-lubing?

Thank you.

Correct. The drawtube doesn't fit same way as on a usual focuser for the 2" model, it is actually rolling against the bearing wheels on stainless rails fitted into the sides of the drawtube. Very slick design and no lubrication required.

Depends on the model. The 3545 used on some refractors is a rack and pinion design and it needs a bit of grease.
