If you are familiar with R, the package FactoMineR allows to perform PCA (with many interpretatitve facilities) and a hierarchical clustering as well (but not k-means). There is also a number of video lessons oh Youtube made by one of the package developers (Prof. F Husson).

Hope this helps

The how part will depend on which software package you are using.

But have you determined what type of clustering you are using? What distance measure you are using etc...
