>1/ Should i keep the files as RGB or convert to grayscale?

Look at each channel R, B, G).  In my experience they will be identical; I've 
found no benefit to keeping RGB, but no real benefit to changing to a single 
channel file except smaller file size.  I don't know what print service 
providers want to print from.

>2/ What dpi/ppi should i keep the files (8 x 10 inch prints)?

300 ppi (2400 by 3000 pixels) if you don't know where they will be printed and 
have specific info for that service.  Some services, for a quantity of B&W 
prints, might make a negative from the digital file.  For that, optimum pixel 
dimensions would depend on the film size and film recorder.  If this is a 
possibility (and if schedule permits) then it would be best to get pixel 
dimension information from the print service when she returns to NY.

B&W grayscale is not the strong suit of most desktop computer printers.  If 
purpose of the prints is in theatre work then best to go to a NY service that 
prints for that purpose, particularly for a large quantity of prints.
