Deadshade: I will send instructions on stitching the images together in a PM so as not to hijack this thread from the main tutorial.

As far as getting the gradient to work, I made a copy of the height map, then using the copy I applied the bump map. The image I used for the bump map was the same layer that I was applying the bump map to. This may not be the correct method of ding things as I am having artifacts on the sides of my mountains that makes them look poo-ish. Once the bump map has been applied, the settings I used above in this case, I then made that resulting image the Temperate layer. Then applied the gradient there.
