I am a little into drifting, my roomate used to go to drift events with his 240sx. He is a damn good driver. He ran -5* of camber up front and -2* in back with some stiff ass suspension and a two-way LSD. Personally, I know about drifting a Supra a bit. If I was you, I would get a stiffer sway bar in back but keep the stock front sway bar and then get some generally stiff spring rates for the coils. A stiffer rear end is a positive thing in drifting, less understeer. I would also run the tire/wheel size I am running right now. some 225/50-17 on a 17x9.0 wheel. Doing that is called stretching the tire and gives you a stiffer sidewall for good steering response but will let you slide good due to the skinny tire size. Just be careful as that steering response tends to give you an artificial feel of traction.
Also, when talking technique on the supra, don't just clutch kick it out. I tend to enter the corners hitting the brakes hard, swinging to the outside hard, letting go of the brakes while heavily countersteering and then once the car kicks around, modifiyng the steering accordingly and putting on throttle. Basically, throttle should be used to keep the car in control, and keep it sliding, not to break it loose.
You may not even need to use the brakes, I can keep my Supra fishtailing on steering input alone. Just feel the weight transfer and let the steering wheel tell you what to do.
