Quote - Hi Gareee
Here are the uv's i use , i still like to point out that i'm using these uv's in 3dsmax with zbrush and that they are working fine for my purpose.
However i don't think you should to much trouble using them for poser.
The Single_Space uv's are the one's i use myself and as you test them in zbrush you will find there's no more overlapping uv's { red in check uv's } after that check fix seams and you can even load the complete texture for V4 and paint the map or like i like to do "Sculpt from texture"

The displacementmaps are created fine now.
The Multi_spaces uv's are the same uv's as the single one only they are layout in the daz manor with the only difference that the uv's are not "stacked but spread" { hope that make sense} and ofcourse the uv's are all fixed.
It's really not a great discovery as you sad rather more a dirty job of cleaning up all overlaping uv's.
What you do find is that a lot of seams are stiched, cause zbrush see's them as overlapping also.
I also provided templates for the single uv's and i hope you give theme a try { i still like to hear if you think the quality is to low } 
The template also gives you a good idea what uv's have been fixed.
For the multi uv's you can still use the same daz templates 
I hope that "Stonemason" can give you a good direction for using The multi displacement exporter 2 from zbrush because i don't have that knowledge.{ hope to learn that from him to }
I hope you have a good idea of my explanation and i would love to hear your 'Experience's
