If you're talking about provisioning/startup of new nodes, just use the
IPs of 2-4 nodes in the seeds section of configs.
If you're talking about clients, then round-robin DNS is one option.
Load-balancers are another. Either could be used with a subset of
higher-capacity/higher-availability nodes, or for the entire cluster.
You don't use just one node, see above.

It's possible to obtain a list of nodes over Thrift. So, yet another

option would be to use a short-list of well-known nodes (discovered via
round-robin DNS for example), to obtain a current node list and
distribute among them.
