Are you planning on reading at least one Bayesian statistics book? Even if you don't plan on doing Bayesian statistics normally (for example, if you've got to share you work a lot), knowing Bayes stats is useful for understanding what other statistical approaches must approximate if they want to be useful. Bayesian stats also includes the very useful notion of Hierarchical Models. They're not taught in intro books (because it can be complex to fit them), but the concept is not hard to grasp from the various introductions on the internet.
