Here are a couple good links to use for Vana'diel world maps. Obviously, there are some details that need changing in accordance with Lykus' ideas, but it's a good template to start with, they're good for different reasons, but in general, you can ignore the standards for each individual nation that are visible on the maps, on the first they are far too large, and on the second, they are not at all indicative of the territories each nation controls.
Map 1Map 2Regarding the technology, I think the technological setting in FFXI is wonderful, so I vote to keep it as it is.
Also, let it be known that I have to put broken image links in to make my URL links work, so if you see one in any of my future posts, that's why.
