Arg. Yesterday, just minutes before the D&D game I'm playing in started, I had answers typed up and ready to post. My finger slipped and hit the "back" button on my mouse. So I hope you can forgive me for the late start on answering your questions. And, to keep my morale up, I'll be starting with the easiest questions to answer.
Oh, can you post a link to Maptool and that Hamachi thing you mentioned?
The Maptool download page is
here. You want to get maptool-1.3.b66.zip.
The Hamachi download page is

Gods: You can pick from any of the published gods or create your own. I'll be using both published gods and some creations of my own. It might become important that 4E doesn't allow spell casters a direct line with their god, so churches can't exactly ask if their doctrine is correct.
Races: There really
isn't a universal culture for each race. Just as humans in real life have a wide range of cultures, each race in my setting has a wide range of cultures. Additionally, kingdoms of a single race don't exist. If an area is prosperous enough for a kingdom to form, it's also prosperous enough to attract immigrants from other races. Single race communities
do exist, but they tend to be found in harsh, isolated areas. If the area was nicer, they would get immigrants, and if the area was easier to get to they would've left for greener pastures.
Malebranche: The rulers and administrators of Malebranche are almost completely concerned with internal politics. Malebranche has huge numbers of portals located close to each other, and as a result Malebranche is part of many trade routes. Malebranche has no resources of its own, and so it must feed its citizens and pay for its army with taxes on all trade passing through the city. To encourage this trade, the soldiers of Malebranche investigate new portals and set up guarded outposts in most of the planes the city is connected to. As a result, trade routes that pass through Malebranche are some of the safest. Traders and travelers are safe in Malebranche, but the rulers are engaged in cloak and dagger conflicts with each other.
