I think I'd first ask why the scanning doesn't seem to be working out. 
Even an inexpensive scanner should be able to do the job.  If you scan 
the image at even 600 dpi you'll have at least twice the resolution of 
the print.  Inexpensive scanners also have fairly low dynamic range but 
so does a B&W print.  I suspect that the scanner is probably capturing 
what needs to be captured but, as with many digital images, the rest 
must be left to some creative post-processing.

That said, I think it would be instructive to also use a DSLR and 
compare the "raw" images.  Decide which is best before investing a lot 
of labor in post-processing.  I would use normal copy procedures (lights 
at 45 degrees on either side and camera perfectly square to the image). 
  I'd take a color image in raw form and do the B&W conversion later in 
PhotoShop.

One possible problem might be pebbled or grained paper.  The pebbling or 
grain can really stand out in the copy but, as Ctein points out in his 
excellent book on restoration, the paper grain can be treated as large 
diameter digital noise and suppressed with the likes of Noise Ninja or 
other noise reduction software.  If this or other restoration jobs are 
important to you I would highly recommend reading Ctein's book "Digital 
Restoration from Start to Finish".  An excellent read for image 
processing technique even if you're not doing restoration.  Highly 
recommended.

ps:  If you've never done copy work with a camera before Ctein points 
out that the old Kodak film era pub "Copying and Duplicating in Black 
and White and Color" is still an excellent resource.  I bought mine on 
the web for about $2.
