Warwick Leadlay is your first stop for old maps of the area. He may have been ousted from his beautiful shop in Nelson Road, but he's set up next door (effectively at the back of the old shop) and he's fighting back. He has several originals at squeakingly scary prices - but also does some very good reprints.
Greenwood's Map
Thanks to the kind individuals at Bath Spa university, this fantastic 1827 map is now available online - see - not everything costs on this part of the site...

Old House Books
Do facsimilies of several maps, but unless you're in the far western corner of Greenwich don't expect much joy from their selection. There is one exception - the rather splendid 1897 map of London's railways which clearly shows London's first railway - London Bridge to Greenwich.
Ordnance Survey have a section dedicated to their historic maps dating back to the mid Victorian age. You can view them online, buy them and even have books made up as presents. Some old OS maps can also be bought from the Visitor Centre.
