Answer 1

Adding on to what's already been said regarding similarity scores, finding k in clustering applications generally is aided by scree plots (also known as an "elbow curve"). In these plots, you'll usually have some measure of dispersion between clusters on the y-axis, and the number of clusters on the x-axis. Finding the minimum (second derivative) of the curve in the scree plot gives you a more objective measure of cluster "uniqueness."
