Ordered my first Quest Pro! Any tips/tricks during setup or accessories :)

Ordered my first Quest Pro today! And so far:

• I already purchased a top mount for one of my Vive trackers
• Purchased the Globular Cluster Kit
• and a battery pack/strap that goes on the back

I more had a question on do I update headset fully once I get it? I see a lot of talk of not auto updating after a point and didn't know if i need to do something beforehand to update to a certain version and even if it is necessary.

Any recs on other accessories I might need or tips for a new user as well. I still have my Index but really wanted to try face tracking.
