You manage pubkeys you trust by signing a message with a list of pubkeys you trust, simple as that.
People can learn about what relays you are on by (again) signing a message that states which relays you are publishing to.
If all relays go down you just send your messages to any other relay.
FYI, a signed message is just a simple json object with string of content, list of tags, time, your pubkey and a signature. “Notes and other stuff”
