Addressing your points;
1) Yes, but I'm not sure why you would want to scale other nodes (I assume you're referring to the masters?)
2) Yes, the cluster-autoscaler will give you more node capacity. If you want to scale Pods on a CPU basis, you can use a Horizontal Pod Autoscaler (https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/ https://kubernetes.io/docs/tasks/run-application/horizontal-...). I believe it now support custom metrics as well, so you can scale on any resource threshold.
3) The ASG/Launch Config is created by Kops when you create the cluster; and is also manageable through the kops tools. It will default to the kops default AMI (which includes the kubelet, and everything you need for k8s to run), but you can also override that with a different AMI if you have a k8s compatible AMI that more fits your needs.
