I forget whether or not I've flipped through Chu's books. I can't really recommend them one way or the other, but I have a slightly negative vibe about them (too academic for what you are -- probably -- looking for).
If you want to develop lower-body power for jumping, I highly recommend Kelly Baggett's "Vertical Jump Development Bible". It's available here: http://www.higher-faster-sports.com/
. Incidentally, this is probably in my top five or ten training books of all time. Seriously. It is well worth the money ($40). KB also has a large number of free articles to either get your started or to evaluate if you like his style.
