D70...and D70S are very good..at least I love mine..
Lenses tho...get the best ones that Nikon make.. there are several ranges..get the pro range as they are quantifiably better....
That being said what are your criteria for viewing?....if its just on screen viewing then that may not be too bad.. but large prints..say anything larger than A3 will benefit from the better ones...I have the old pre digital ones which where in the £350 brakcket 9 years ago...and images taken with these can be taken to A0 print size easily....
