You don't need to run your own mempool. I've had performance issues with it on umbrel.
You are probably using Tor with your umbrel so don't need a firewall unless you configure it to use clearnet.
You don't need to configure bitcoin node unless you are a power user.

How do you mean “I’m using tor”?

I mean. I know what tor is. But do I use it with Umbrel? I don’t know
Tor comes preconfigured with Umbrel so you will be using it.
Oh right. Thx!
