making it sway side to side is not done by the brakes. it's done with the steering wheel. braking is used to transfer weight, putting weight on the front allows front to turn in, loosening back for oversteer situation.
the left/right/left flick is the feint drift, but i'm assuming you want to link 2 corners together using the flick, thus, when you exit the 1st say right hander and the left is coming towards you, you could use the suspension rebound from the 1st right hander to induce oversteer for the 2nd corner.
clutch kick is not a lousy technique. it's used to overcome understeer and if you'd download some jap drift videos, you will hear the obvious rise in rpm when they dive into a drift, which is the clutch kick.
locking up the wheels, is again, another technique used to drift, which is called shift lock. using excessive downshit without heel toe to balance the car causes compression lockup which locks the rears.
there are drift setups for cars, but i assume these cars won't be driven on a daily basis. excessive camber and toe out would not be a good thing for a car to have on the highway.
