Digital BW, The Print

I want to digitize my archive of monochrome silver prints (for ink jet
printing, so not too off topic). First thought is to shoot them on a
copy stand with a DSLR. All were originally shot on 35 mm. film. Do
you folks think an 8MP Canon is adequate to make prints comparble in
detail to the originals, or should I rent a 12MP body, or what?
Scanner for the smaller ones? Thanks for any advice.
