Now I’ll get to the few questions, perhaps a little bit specific 
Is it possible to smooth only selected body parts with DAZ Studio built-in mesh smoothing?
No.

Why there are so many different properties in the tabs hidden (i.e. the mesh smoother and it’s detailed properties)?
Good question.
I am only guessing that they might be there for other advanced functions I have not discovered yet.
Or they could be there for the future. Still a good question.

And is it possible to unhide them by default? When I unset Hidden in the parameter settings its just for the current scene.
Generally they are hidden for a reason. In 3 years I have never needed to show Hidden. Anyway from what I can see it doesn’t stick as soon as you reopen Daz Studio the revert back to Hidden as you found.

What exactly are the p<Morphs> and JCM<Morphs> for V3/M3?
Morph, simply put is to change the shape of said object…to morph it in to a different shape. JCM’s are Joint Control Morphs The for V3/M3 means Victoria 3 and Micheal 3, Generation 3, we are now on Generation 5 with Genesis.

How to create sweat on the skin with the built-in shader-capabilities in DAZ Studio?
Are you talking about the Shader Mixer or the Standard Advanced Surfaces Pane?
There are Wet Maps for V4 http://www.daz3d.com/shop/universal-wet-maps-and-orcamaid/ which work in the Normal Surfaces Pane. Not sure what is on the market on other content sites for other figures. What this is I think is a bunch of Specular Maps to give the illusion of wetness. I don’t have the product myself.

During experimenting with ambient, diffuse and specular color values I didn’t accomplish a convincing result.
Hell, how they depend upon each other… :-( Do you know some written tutorials?
They don’t up to a point. The all work separately to give the “whole” but Bump and Displacement can affect the specular highlights and make reflections more blurred.
Try this one for a little more help with the Surfaces Pane The different bits of the surface tab.
