In this tutorial I will mainly be covering how to alter bump and displace settings for MAT's applied by Poser files so they display correctly in Daz Studio, but will touch on the other surface materials.
I thought I would start with a brief, somewhat simplified explanation of how Poser 5 and 6 handle material 'maps', and what changes may be needed for a similar appearnce in DS. I am going to assume that you know how to apply materials in P5 or P6, and DS.
 There are several different maps that you would commonly use, and they consist of colour or monochrome jpg files that you attach to nodes in the material room of Poser, and in the surface properties of Daz Studio.

What is a Diffuse map?
You could consider this the base texture of an object. For example, in a dress, applying a yellow polka dot jpg here would give the dress a yellow polka dot appearance. You do not have to adjust this, generally, when applying the same texture in Daz Studio.
What is a Specular map?
The specular map is a representation of light hitting the surface of an object - a higlight in essence. It is not the same as reflection - simply a way to add a sheen to an object. For example, a dry clay brick would not need specularity, but a wet marble surface might.
What is an Ambient map?
The ambient map is a 'glow' effect you can add to certain parts of an object. Khory has already written a great guide on how to use these, right here!

Now here is where the two applications really start to differ!
What is a Bump map?
A bump map is a monochrome texture that simulates 'roughness' on an object. In Poser, the black (0,0,0) on a map represent lower areas on the surface of your object, and grey to white (255,255,255) raised areas on a map,'bumps' in that surface.
As you can see, a bump map does not actually alter the shape of the obj structure, but uses simulated shadow and colour changes to give the impression of raised sections. While sometimes, this can be effective, it can also make it difficult to tell whether an area is raised above, or dropped below, the original surface. (A bump or a dimple in other words!)
If you are trying to create a sheer edge, you must be careful there are no grey pixels between the black surface and white bumps - or you will get a gradiated edge.
