Good keyboarding skills are useful, but also pretty easy. Spend an hour or two reading and watching about how to do it properly, and then spend 30 minutes a day on PAWS, Mavis Beacon, Mario Teaches Typing, Typershark or The Typing of the Dead for maybe a month. Paying attention to your posture and proper technique more than everything else. Put a (paper) file folder over your hands so you can't peek.

Get an ambidextrous mouse, and try left mousing from time to time. Try to left mouse at work, and right mouse at home to give your body more variety. Use page up/page down to scroll instead of the scroll wheel; scroll wheels are super useful, but ergo nightmares.

But, that's not going to help your work that much. Work on effective communication, which is gathering information from others as much as it is providing information to others. Sometimes the other is yourself. When you see some writing or speaking or drawing that communicates well to you, study it, and think about how you would have done it, and what you can do differently to be more effective. Practice this as well. Maybe you see a manual that's terrible. Can you spend 30 minutes redrafting it and another 30 minutes communicating with the owner to get it updated?
