I have yet to find something I like. In my opinion, ISLR (Intro to Statistical Learning with R) and ESL (Elements of Statistical Learning) give the mathematical details but don't really provide much advice on what to do in practice or how to do inference on clusters. I've been playing with mclust recently and am pretty happy with the results.
In terms of just getting answers in R, you might also appreciate the Practical Guide to Clustering in R, which is fairly short and rough, but has some great example code for creating nice visualizations.
