I will attempt to help as I have created numerous modules for Star Wars Rulest for my home game:
1. You simply need to add any images and maps to the Campaign Folder Images folder. That folder can be difficult to find. For me it is located here: C:\Users\<computer login name>\AppData\Roaming\Fantasy Grounds\campaigns\<campaign name>\images. Once copied into that folder, then they will show up in your images tab. you may have to resize the images and maps in an image editor for best view. The ruleset has a limited imaging resizing function, although it does work.
2. The GM Encounter Library has numerous NPCs avaialble to choose from. It is located here:

Go to the second post and you can download both the Player Library 2.0 and the Encounter Library (GM Encounter Library). Both have what I consider essential data to get your game up and running quickly.
3a. Go to
https://www.fantasygrounds.com/forum...a-Token-Module for a tutorial on making token modules. Making a module is the ideal way, especially for large numbers of tokens. It alleviates the memory problems caused by too many tokens in your token folder.
3b. Here is a good thread for Star Wars tokens. Some of the links have hundreds of tokens available. I used them and made my own Star Wars token modules using the video posted in the link in 3a.
4. I manually keep track of them so hopefully someone else can help you with this.
