Ash those parralel groves on the draw tube are caused by the bearings inside the scope that contact the draw tube.
Realy a consequence of the design. I have them on my MooLite focuser too.
However the scratching on the Lunt seems very excessive considerring I guess you have only used it a few times.
As for the rest it does look like poor quality control.
I would be going straight back to the supplier with your concerns.
