Get some kind of network storage, or dedicate a PC to share storage on. That way you're always pulling the data from the same place and if you make any changes it'll be in one centralized location. It's easy to do with Homegroups in Win 7, or you could buy/build a NAS. My personal recommendation is to either go buy a book on a good entry level test (Network + or something similar) and study or check your local college for a course. My brother in law is getting into networking and is taking the Cisco Academy class at a local college. It's pretty inexpensive and he'll get to take the exam for free.
