Thinking of picking up a Nikon D3100 at the weekend but I don't know if i should go with a kit lens or invest more of the budget into getting a couple of really good lenses to go with it so that if / when i get better the lenses won't let me down.

I am primarily interested in photographing faces, and particularly for printing in B/W.

for reference i consider myself a beginner as it's been a while since i picked up a camera in anger and the last one i owned was a Ricoh KR5....... student budget!
