Editing and replacing the map is quite simple to do. You take out a copy of the map.png file in the mod's jar, edit it and replace the default one with your custom map.

Adding new factions is a matter of modmodding and that requires java coding skills. If you don't have them or are unwilling to learn it with a lot of patience, I recommend not to even think of it.

Regarding modding of the mod, there's this recent thread that holds a lot of info on what can and what cannot be done.
