Saga Edition Resources
Check out the great Star Wars RPG Index, with lists of all the species, classes, talent trees and equipment available. For each one, it points you to the proper book and page.
Need a quick reference of Feats? SWSE.Wikia.com is searchable. Other parts of that wiki are far from complete.
Also note that some of the rules in the books have been corrected since their first prints. The official errata tracks and clears all of that up.
The role-playing haven that is Myth-Weavers.com has come in extremely handy with its interactive and share-able character sheets. Don’t create a character sheet in Excel without trying this out, first. Note: For some reason, the “Create Sheet” button may or may not work with Firefox. Use another browser to do that part, and the rest works just fine.
