I don't use DWF, but to get correct scale in DWG you have to set the DWGUNIT correctly for the reciever in your translator.
To have full control over pen colors in the DWG file, you need to use the Keep Index Number translator and check and perhaps customize the included pen table. (If you customize, do it on a renamed copy)
