Resource #1: This is the Star Wars 5e wiki. It's free. All(?) the rules are here. You just need to be a little bit familiar with Star Wars and D&D 5e.
Resource #2: This is the primary map I'll be using. I have no idea how well in conforms to the other maps out there, but this seems to be the most usable one.
