Swimming drills--training suggestions?

I answered a questions like this in a similiar post, try this:

You can build in drills into the 'minutes' given in the plan via Total Immersion or some of the articles here: http://www.beginnertriathlete.com/cms/index.asp?catid=19   just pick a short and/or medium swim workout to focus on some concepts and use a little bit of the long workout to re-enforce them at the beginning and finish with some long sets.

Kevnin Koskella has several 'lessons' that you can build-into a workout:
