  I find the front view is the most useful in making sure feet are at the right level (you can see the ground planar level as a straight line). There is no ground collision mechanic.

  You can't really use two different characters skin a the same time the seams won't match up nor will the skin tone etc.

  The things that effect skin appearence are lighting and the surface settings.

  Here is a basic guide to the surface settings in DS
  http://homepage.eircom.net/~neilvpose/ds-settings.htm

  Its for an older version of DS but is still relevant.

  A lot of the getting it how you want to look is trial and error.

  There are several threads about the forum discussing lighting and surfaces especially skin its worth while reading them.

  In this months new users contest WIP thread I also give some basic settings and advice on setting up skin for rendering in DS http://www.daz3d.com/forums/viewreply/210689/ which you may want to take a look at

  Well not fully true, you can use two different Skin textures if the textures are both for the same Figure. Example you could mix two V4 skins on a figure by loading the different textures onto the proper areas in the Surfaces tab. But as stated the Tones might not match from one texture to the next. But it can be done this way.

  Actually you can use the limbs from a M4 texture and the torso from a V4 texture as long as you set the UV correctly. I've done it in order to create a certain look, but I wasn't going for 'realism'.

  I keep for getting that DS4.5 added that feature. I'll need to remember that tip for the future.

  I was doing it before 4.5 UV swopping came in with Genesis and DS4.

  For example, I managed to render this woman portrait I attached, using uberenvironment and the 3 lights setting that was recommended here for portraits.
  The problem is that in this render, her face and hand are pretty close to the result I'm trying to achieve, but the rest of her torso looks awful in comparison. It's yellowish and doesn't look real at all, while the hand and face look much more real and have a nice skin color to them.

  Is it the lighting? is it something else ? what is causing this? How do I affect the way skin renders?
  I'm trying to experiment with stuff until I get the right results but I'm really confused and want to know what I'm doing, instead of just randomly trying things and wasting time. So this is my main struggle right now.

  
  I would guess the yellowish areas you are seeing on the torso are specular highlights.

  Select the figure, go to the surfaces tab, expand the figure and select the skin torso settings.

  First I would check the textured used in the diffuse channel to make sure the yellowish color is not on the texture map. I think this is unlikely, but if it is, then the only way to remove it is to edit the texture map in a photo editing program like photo shop or gimp(free).

  Assuming this is not in diffuse skin texture, I suspect the yellowish spots are specular highlights. The tutorial linked to by scorpio64dragon does a good job of explaining the interaction of glossiness and specular strength. Try turning the specular strength to 0 on the skin torso and re-render the image and see if the yellowish goes away. If it does then you can adjust the specular strength down and change the color of the specular highlights till you get the look you want. You probably will want to make similar changes on the other skin areas too. I suspect the reason you are not getting the same thing on the face and hands has to do with the angle of the light and the shape of the face and hands.

  The other thing some vendors do is add a little bit of color in the ambient channel. This of course is not real. Human skin does not glow in the dark. But I have seen skins with ambient strength set to 100% and a color like 20,0,0, which is putting out a small amount of red light, to give the skin some "pinkish glow." I have also seen skin textures that setup a stronger red or pinkish ambient color, but have the strength at 5 or 10%. You can affect the color of your skin areas this way too, but this effect will vary with the lighting of the skin.

  1. Can I use 2 different skin textures on one figure? Some "characters" I bought on renderosity come with textures that affect the way their face looks...without the texture the face looks different than "advertised" for some reason. However, sometimes I want to keep the face but don't like the texture on the rest of the body.....can I replace it with another one but keep the face with the appropriate texture?
  

  I have a few skin textures from figures I bought at Renderosity, and they do not render very well in DS. I have to fiddle around with the skin surface settings a lot to get any kind of acceptable render in DS. I suspect that the presets they include are for Poser, and Poser handles lighting differently than DS, so Poser values do not render very well in DS. I think DAZ makes vendors that sell products through the DAZ store create different presets for DS and Poser in their products.

  
  2. When manually posing figures, I often struggle with aligning whatever limbs are supposed to be touching the "floor" to the actual floor line.
  Can the "floor" grid be set to be non passable, meaning that the figure or any of its limbs cannot dive under the floor ? if not, is there another solution for making it easier?
  

  I don't think there is any magic for this. After posing the figure, you just need to get down low with the camera and adjust the hight. As long as you have it close, it will look fine when you render it.
