tranny ?

I got a racing clutch in my car right now and it's driving me nuts...lots of clutter in first gear and and i cant ingage at low rpms or it will shake the car, i was wondering if i could get a regular clutch disc and reuse the pressure plate that i have in there now....could that work...anyone an engineer that can answer this? I also want to put a lightened flywheel into my car but i'm not sure if i should use a regular clutch kit or i need to use the heavy duty pressure plate taht i have on there now
