I can probably contribute a few things to this. Are you planning on creating a sort of catalog of props and ships as well?
Some ideas that I've run into from time to time:
Most home worlds name themselves for their local word for "dirt" or variations of ("That Which Holds Our Roots" being one), which has lead to a lot of confusion. Interstellar travelers should know the hexadecimal catalog number for their system and world to avoid destination errors.
There are multiple Earths. Each started identical to the other, but have developed different cultures over time. Only a few of these Earths are aware of each other, most insisting they are the original. Each system has a gas giant. These multiple Earths are sometimes called Seed Worlds. Interstellar travelers should know the hexadecimal catalog number for their system and world to avoid destination errors.
