I want to create a tangent space normal map, but the image that xNormal produces looks like it has too much color or something. Am I doing something wrong? Also the entire mesh has only 1 smoothing group (using 3ds max)

"Do you know what type of problems could be happening with the normals on my mesh's? Also I was not aware that the normals of the high poly were relevant when baking, any insight about that?"
It's hard to say what is wrong with your normals or why, or even if that is the problem here. You'll have to debug the meshes and see if the mesh normals make sense. You could try freezing transforms and resetting the mesh normals, and checking your export settings as well. This varies depending on the app.
As far as the high poly mesh normals go: when you're baking from high to low, what you're really doing is transferring the high poly mesh normals to the low poly mesh normals, so the normals on both ends need to make sense for this to work properly.
