Main tip here is to turn off sonarworks and move forward with minidsp instead. SVS 2000 pro has a dsp so you can fix a lot of your room in one go. As for the cluddy mix the main tip I can give is to set your vocals in only while the drums and bass are playing back. Use the "we will rock you" feeling. If your main mono signal is balanced the rest will be easy to fill in just via panning and imaging.
