Compound surface issue

Hello,

I'm trying to resolve some issues with this object. My ultimate goal is to convert this to a poly mesh for further editing in Blender.

However, in it's current state, when I convert it, the mesh is pretty chaotic. Take this corner for example (in yellow). I don't know how to properly describe it, but in polygon terms, there is a lot going on with the edges in this area. There are subtle things happening that when it converts, creating a lot of overlapping geometry (see red arrow).

So what I hope to do is to delete some faces and use some MOI operations to restructure the corner in the screenshot. But I'm not sure how to approach it. I included a Dropbox link to the 3DM, STP, and also the converted OBJ file.
