I think you want us to make the decision for you. But we can't. Only you know what you want...
But, for the record, as far as DSLR lenses go, here's what I did:
Nikkor 18-55 kit lens
Nikkor 70-300 tele zoom
Sold both and bought
Nikkor 18-200 VR
Then bought
105mm Sigma macro
10-20mm Sigma wide angle
Then got
Nikkor 50mm which was included with my D200
Can't see how this helps, but there ya go...
And what did I find most useful? All the lenses I now have. Cos if they weren't useful, I'd sell them...
