So there re two possible issues. One is gaps that prevent spaces from being made. There are tools for both SketchUp and Autocad that can find/fix gaps, but it is not always as simple as a click, there may be mistakes in how it is "automatically cleaned.
The second issue, is a model that may be valid/clean but way too detailed producing tongs of tine surfaces for subtable envelope offsets that you don't want. I'm not aware of an easy way to do this. There are many DWG/DXF polygon reduction tools, but most of these are focused on 3d geometry, not sure hat it would do on floor plans of multiple polygons.
Your best bet depending on scope of the issue is to live with the high polygon count, or maybe manually trace in SketchUp, but only with level of detail you want. You can group the DWG import and lock the object. Then you can still snap to it while drawing (so better than importing as image).
I know Autodesk is trying to provide some level of geometry simplification for what they call "Analytical model" in Revit for energy analysis. but not sure if that will help you for the current project.
