Thanks Gandwarf and Coyotemax! In regards to final size, I am not sure. I noticed some very nice maps like the one coyotemax did for new dawn of the west were very large, but the amount of detail is awe inspiring.

The end result for these maps is to be viewable in a 960 width window, which will be the length of my interactive viewer window. I need to check around and see what is the norm for post work on maps, I know on my kromgor map, I got squeezed for space on names. If i went lower on font size, it becomes hard to read, unless I did my labelling in Photoshop, where i could go lower in font size and make it readable.

If my maps go past 960 in width, then I would need to support sliding around like google maps. I have not decided if I want to go that route, although I have a prototype that can view any size maps (uses tiling and ajax like google maps).
