This might be the silliest collection of questions but I have limited CAD experience (Tinkercad) and started OnShape just few minutes ago… Please apologize:
(1) I wish to substract two solids. I sketched, extruded and trasformed (moved) two solids ("parts"), but when I want to substract ("remove") one part, it "jumps back" to the original position, before I had moved (trasformed) it to the final intended position. How to avoid this?
(2) I would love to see a sort of "grid" or optionally a "live position coordinates" of my pointer while I am sketching, before I clic anything… Is this feature available?
(3) Is it posible to move (translate/transform) sketches BEFORE I extrude them into a solid, or only solids can be moved to new a new coordinates?
I am currently stuck with this and would appreciate

I would suggest going to the learning centre and going through some of the courses there.
It's unclear to me why you'd want to move solids, sketches etc directly after creating them. I'd suggest you create them in the proper position in the first place. There is a move command in the sketch dialog, but it moves the lines in the sketch, not the whole sketch.
one other way would be to create the sketch on a mate connector iso a fixed plane, and move that mate connector. again this is before the sketch creation
Your questions are all related to the way that modeling is done in Tinkercad, which is very different from a professional parametric modeling platform like Onshape. I would start with the Onshape Fundamentals Learning Pathway. That said…
I see your point and it is true: repositioning a solid could be needed due a simple editing need but in my specific case as a beginner is to locate the solid in the final intended position in a "2nd step" because I fail yet to precisely locate it from the first shot because I miss a grid or a live coordinate to know "where I am"… In a precise example, if I create a cylinder, I fail so far to find the menu that shows me that the cylinder center is located in (X,Y,Z) and that has a diameter of D and height of H. If I would have this and I could edit these parameters by typing in values, I would be set.
About the learning centre, I truly gave a (maybe too short) try but gave me more the impression to be more an exhibition of feature and less a training plateform. I may need to retry/research.
Dimensions. To create a cylinder located at xyz with a diameter of d and a height h, sketch a circle on a plane at the desired z. Add a dimension to the circle to specify d. Then add dimensions to the center of the circle to specify x and y. Then extrude it a height h. All of these can be edited later.
