After updating firmware, I will also suggest practicing navigating the menus. They are not totally obvious at first, but just be aware of what you might need to change, and give yourself a bit of experience changing it. For instance, Line/mic/Phantom power on, track arming, and be sure your record mode is as many bits and samples per second as you like.
Others:
Set the date and time... check how you like the files named, I go by date.
Also... I trust the limiter. I try not to slam it, but I'm glad it's there.
