Or for that matter linking to the gallery page/image.  

Quote - longhorn : 1. If I'm using pieces and parts of old meshes from somewhere I can't remember where they came from and they're rebuit and re-textured, is that a copyright infringement?

It depends on what you intend to do with the reworked mesh, and what terms were specified for the original bits and pieces. (Re)distribution is a non-starter, unless all the original pieces permitted reuse (very unlikely).
Commercial use of any images would also be reckless unless you're sure all the original pieces permitted it.

Quote - longhorn :2. How can I get Texture maps for major sections? I've tried UV mapper but it's being extremely difficult. ie. splitting layers and such. Any help would be appreciated.

Ask for help in the -> UV Mapper forum, UVDan (and others) are very helpful to beginners.

Quote - longhorn : 3. I've got the making prop stuff down Ok, but I want to make this a figure. Is it better to place all the pieces together or explode them before entering the setup room? (this is where I really have troubles, character /skeleton creation.)

Basically you should have all the required polygon groups and materials defined before trying to rig in Poser.
Whether or not the mesh will need to be welded depends on many things.
See drgeep's, PhilC's and others' tutorials for an introduction to all the various things you'll need to tackle.  

Quote - longhorn : 4. Lastly, as a prop, I had to make a CG (center of Gravity) mesh to keep it from going weird while rotating and such. Whill I have to include that in the figure or no?

Sounds like all you really needed to do was adjust the origin.
