Giving finger prints does not mean anything. Currently, I-140 and 485 can be submitted at the same time. Once your 485 filed, you may be required to give finger prints. If your 140 is denied, your 485 and finger prints will be in vain.
You can apply for your coming back permit when you are filing 485. It just depends on when you file your 485.
