Others will chime in about the "clunk" but what you have described may not be normal. Most of the classic "M clunk" happens at low speeds..low RMPs in low gears. Having it all the time is not normal. Did you get a PPI? If so, did they check the rear subframe mounts?
RE: the navi screen...I had that happen on my 04 ZHP. Not good. The pixel defect will grow over time and I was told that it is not fixable. The only remedy would be to get a new screen/front section for the nav unit. Not cheap.
