I sometimes type up my drills and focal points and put the paper in a zippered plastic bag (or one of those full-size plastic page protectors) & take it to the pool with me. Put it on a damp kickboard at the end of the lane, and I'm good to go.
I also have Coach Brian's set of practices for beginners, though it's helpful to have the basic drills down before you start these. They have drills and focal points along with the goals of each practice. You can find it in the TI store under the books category. It's actually a PDF file you can print out.
