One of the things I'm having a hard time with is figuring out the "Cultures" in character creation. I've found the map of the playable area of the game, but is there/will there be a map of the entire world? It's hard to get a handle on where all of these cities, bays, islands and continents are in relation to each other. When asked what culture I want to be from, combined with my race, I'm just randomly guessing, which really kills role play immersion. Even the wiki is pretty vague on the details.

I agree, a map would be good.  There are clues as to where things are in the descriptions of the cultures, but a map would be better.

I'd even take a fan-made one, at this point. Maybe I should try to draw one up in Paint.net, using what little info I can find
