Okay. With regard to game models Im not really that savvy as I work in the film industry...but techniques are similar for higher res models.

Usually we import an obj into Zbrush and then do a sculpt, paint maps or whatever. To create a nice texture, normal or displacement you have to divide up the geo to get a good result, this will then give you better quality maps. To export the model from zbrush scroll down to export open the options out. It should be defaulted to Quad, Texture, Merge and group....just turn off 'group' then go back to the top of the tools menu and hit export. Baking maps can be done in Maya but you can export the same maps in Zbrush alot easier after you sculpt. For your UVs, its best to do those in Maya first. Dont touch the UV buttons in Zbrush unless you have to though, usually good uvs from maya are going to be more benefical than those in Zbrush as they are better for editing. If you turn off uvs in Zbrush from a Maya imported model you will lose the uvs!! Be warned.

In maya you can add a smooth to the lo res model if you want when doing displacements. Normals are best displayed thru the High Quality render setting in GUI. This should allow for you graphics card to display the normal map in real time....
