Ok. I cleaned up some of the edges which helped in the lower area. For the upper area, I guess I am still unclear what to do as far as splitting the face. When I split it in half, one half appears to look okay. Not sure where to go from there. I tried deleting the face and then extruding/merging the edges. That appeared to make it worse... face turned black???
Here is the updated poly mesh with the edges removed.
This is what it looks like w/out the wireframe.
This is what it looks like after the normals are averaged. It appears to have fix the nonplanar face. However, black spots now appear on the side. This doesn't really surprise but now I am unsure how to approach this issue.
