How can I use Geth (or any other client) to get a list of my peer nodes on the Ethereum network. I see there's a function to get the number of nodes using the web3 api, but I need a list of node IDs or IPs.

Use admin.peers to get a list of the currently connected peers:
> admin.peers
[{
caps: ["eth/61", "eth/62", "eth/63"],

This admin.peers property and other management APIs are documented on the go-ethereum wiki.

Paste this line of code into the geth console to get a more concise version:
admin.peers.forEach(function(value){console.log(value.network.remoteAddress+"\t"+value.name)})
This will display something similar to this:
