1996 Honda Accord Which clutch kit to buy

Lately when accelerating in my car I notice that the rpms go up but the car doesn't accelerate more so when cold then after it has warmed up and been running for a while. So I am thinking my clutch is slipping I think I just need a new clutch kit as the pedal play is perfect and I don't have any problems shifting the car in any gear just seems to not grade when I get it too much power. My car is also lightly tuned ram intake, high flow cat, 2" catback exhaust, 9mm spark wires, and platnium 4 plugs. So my question is should I buy a performance clutch with an organic surface or have I not maxed out the grab ability of an oem clutch. Also aobut how many hours of labor are invovled in a clutch swap?
