Weinstein is a wonderful teacher, but very old school, and very "my way or the highway." He's also a little too German profile and too "tip down" for my tastes. Your knives (Global, Fujiwara) are French profile and not ideal for you to copy him exactly. There are a lot of different, equally valid styles -- but you could do a lot worse than learn to learn and adapt skills from Weinstein.
If you want to know all about knives, sharpening and kit as well as knife skills, go with the Ward book, it's excellent. But again, be aware that there a lots of equally good ways to skin any number of cats -- and Ward doesn't have a monopoly on them any more than Weinstein does.
A very high percentage of knife use is really just using a very sharp knife which is well enough designed for the task so it doesn't fight you. Still, the whole pinch grip / claw / cut and retreat thing will make your life much easier -- and while it isn't the only way to chop, it's relatively easy to learn and very efficient.
Read Getting a Grip, and Guillotine and Glide, also check my blog every month or so for knife skill additions.
