To answer your question, by the way, if I was doing this, I would use Adobe Illustrator and/or Photoshop for the grids and key. That's the best and most flexible, but it may be overkill, and costs at least $19.99/month. (Though there is a free trial.)
For moving tokens on the tabletop or online, I think the alphanumeric numbering would be less necessary—you may want dedicated software like Roll20 for that.
Fantasy Grounds has the whole module ready to go, for less than than the book or the maps by themselves. I haven't heard of people using that face-to-face, but it might be worth a shot.
