Here are the chapters of Notre-Dame de Paris (1831) that first brought us Hugo's spider metaphor, in French and in English (here and here).
The locations in this episode are not new to us, so they're already on our Google map, but you'll have look for them in the Part II layer.
And finally, here's a website with some pictures of the sort of small pistol that is probably quite similar to the ones that Javert would have given to Marius in this section.
