It gets easier. Give it a little time (and practice) and you'll have a lightbulb moment where it all starts to make perfect sense.
I teach classes, and for the first two weeks of my intro class all I talk about is exposure to people with glazed eyes and baffled looks. To a man, though, everyone gets the idea by the end of the course and exposure becomes almost second nature to them.
I haven't read that book, but the easiest way to get your head around exposure is to put ISO right out of the equation (set it to 400 and forget it) and just work out the relationship between shutter speed and aperture. Once you understand how to balance the relationship between them, work out the differences between the metering modes, and once you're all set with that start working on ISO. By that stage, it'll all start making sense.
Also, either set your camera to adjust exposure in full stops (instead of 1/2 or 1/3 stops) or memorise the full stop increments for each of the exposure controls. That way you'll start getting your head around the effect that altering one exposure control has on the others.
