I'm not sure why you are worrying about sharpness of the lens. Those are nice zooms made by Nikon. They are good enough for 35mm film photography so they are definitely sharp enough for HD.
All I would worry about is having enough light. If you have access to lighting gear, the world is your oyster. You only lack the ability to open up to a wider aperture.Remember each stop you close down requires twice the amount of light to expose properly. Just saying that the difference between my f/1.4 primes and your 2.8 zoom is 2 stops, which would require 4 times the amount of light. Just to put it in perspective.
Like I said, many people won't go over 2.8, and I think you can pull off a 2.8 lens as long as you always prepare with ample light.
A word of warning, one of those zoom lenses looks really long, I'd look into a lens support for the rod system to help relieve some torque on your lens mount. I would wait to see if you need it, but you might.
