What you are saying is what i am finding.. I do have SkyHD and at the moment have the settings I listed above. Although they are more than adequate I am still tweaking.. I will try your settings and see what I think.
My biggist Dilemma is Xbox 360 on VGA..Its washed out compared to composite. Apparently its a trait of the Xbox output. Ive just received the HDDVD xbox add on so over the weekend i will draw my final conclusions on how to connect it (Ideally I want to keep it on VGA for the DVD upscailing and to keep composite free). You can make the VGA more vibrant by having the light sensor OFF but I prefer this ON for all my other settings and its a global setting.
Basically what im finding in the week ive had the set is PQ is excellent and clean with good blacks. The 2 issues for me (which are minor) is the colour setup and the Xbox into VGA. I think another week of tweaking then that will be it. I can get on with setting me audio side up then and weather to mount it on the wall or not
