Whoa! whoa! too much information!
If you use hardware render with the normal map connected to the bump channel (in the attributes for the bump node, there is an option to use the texture as tangent space normals in one of the drop-downs) it should show up.
You'll probably want to give some more time to your shader to get a result that looks good though. I recommend a CGFX shader like Kodde's at http://www.kostas.se/shader which will let you apply all sorts of things to your model when you're ready, and look good in the viewport.
Yes, I am using tangent space normals and it looks good in Maya. However rendering is another issue. So far my solution is to use one dir light and adjust the normal map "alpha gain". Works well so far. I am just rendering one image.
