Back when I was in chicago, we had the Guild for the Blind, which offered computing classes in JAWS and window-eyes, if I recall correctly. The services around here are available, but I just.. never saw reason, personally. I'm a learn by doing folk. :P
I figured out jaws by myself. There's oodles of sets of instructions online that help you figure out navigation tricks that save you time, like typing "e' to get to an edit box instead of wading through the entire page, ect. once you learn some basic keystrokes, figuring out the braille display (noting, this one -is- an older model, no fancy navigations) is as simple as testing out the very limited navigation keys on the device, reading it's manual, ect. I learned over time, eventually (and slowly) switching over from big fonts -> zoomtext -> braille as my vision got worst.
