If you're on a once in a lifetime trip good glass is critical. For a small kit AND all 2.8 glass on a D70 (or any DSLR for that matter) I recommend a Sigma 18-50/2.8EX and the 50-150/2.8EX. Take a teleconverter and have a blast.
My problem with all-in-wonder lenses like 18-200's is they suffer from softness or distortion at the extreme ends of the range. Either way, most any lens now will take good pictures and talking about edge2eedge sharpness and all this is splitting hairs. The most out of focus thing in a photograph is usually the photographer.
Good luck with whatever you choose!
