I personally use the Star Wars "tiered canon" system from before the universe reboot as my guide to sorting out continuity.

Anything that appears in the series or commentary is the top level of canon - fully confirmed.

Soundtrack and content revealed on internet sites, even if connected to cast, is the second level of canon - possible, but not always 100% accurate.

The third level of canon is the heresay we see a lot of, while fanfiction and fan creations are below that.
