The pictures in your gallery are very nice.
From my experience, the sharpness and general quality of an image are more strongly affected by the lens than by the camera you use. As an example, I got much better captures with the D70 plus the 70-200/2.8 than I did with the D200 and the 18-200.
When I was using DX cameras with consumer grade lenses, I found that using the DxO Pro raw converter with their default preset vastly improved sharpness and IQ. You might want to explore this. DxO offers a free trial.
I have been using the D700 for about four years and I see no need to change to a D800. The 12MP of the D700 are ample and give tack sharp images on my 30" monitor, if I use high quality lenses. My sharpest lens is the manual Zeiss 100/2. I use this lens preferentially together with the Zeiss 35/2 and the Nikon 14-24/2.8. I believe this is the best combination of sharp lenses available, unless you want to capture fast moving objects; that would require AF. I believe that manual focus together with LiveView gives you the sharpest possible focus.
