So have you gotten your answer yet about what the difference is between the D800 & D800E is yet Gerry?
If not, basically the E version doesn't have an AA (anti-aliasing) filter over the sensor. If you do any kind of google search on the comparison between the two, you'll see that the E version is actually very noticably sharper than the non-E version.
I had the D800E for a few days last week to test out & man, its so sharp I bled. That backed by being so sharp at such incredible resolution -its no wonder I've heard many people say the D800E is the medium format killer. With all the benefits of a 35mm system of speed & reliability.
Of course, you do need the glass to extrapolate all that image data. I don't know too many of the Nikon lenses, but I used the 14-24, 50, 70-200 mostly. All of those lenses were sharp from end to end & handled the resolution very well.
Just to comment on this pages lens recommendation, I must say that yes, if you do own a 70-200 you will shoot 99% of your work on that lens. Not because you look awesome with a mother big lens, but it gives the nicest (in the zoom category) results for people work. Even 70mm on a FF has a pretty wide feeling to it.
