The D7000 with the AFS 18-200mm lens is an excellent kit. I have had my 18-200mm lens a long time and find it's a very capable lens. I find it's very sharp all the way to 200mm. Others here will tell you it starts getting a little soft toward the long end but I don't find that to be the case with mine.
You can use most of the manual focus Nikon lenses made after 1978 or so that have the AI indexing feature. Do you know if your old lenses are AI? Lenses that are not AI will need to be converted to operate on the D7000 otherwise you can damage the camera. One of the ways to tell is if the meter prongs have little triangular cutouts on each of the prongs. The non-AI prongs are solid without cutouts. To use these manual lens all you need to do is add the lens focal length and aperture into the non-CPU lens data in the Setup Menu. That will give you accurate metering and the accurate aperture readout in the upper control panel.
Your old 50mm f1.4 lens is quite capable and might be a little sharper than the 18-200mm but even though I have both lenses I've never compared them.
