You will definitely need a flywheel puller for the flywheel, no way around that.
For the shift clutch, you won't need any puller as it's not pressed on, but you may need the tool to hold it with while you loosen the nut. You can hold it with your hand if you have an air impact wrench to loosen it with. That's how I do it, anyway.
For the centrifugal clutch, I've never needed the puller tool, but you may need it. Seems a lot of people have trouble getting them off. I usually tap the outer edge with a hammer to jar it and then grab hold of it with both hands and pull real hard. You might be able to get a pry bar in between the shift clutch and the centrifugal clutch and pry a little bit to get it started, but be careful, the shift clutch is made of aluminum and it would be real easy to break a piece of it off. Some come off easy and some not so easy. The centrifugal clutch is pressed on but it's just a light press. If you can't get it off like I described, you will need the puller tool.
