flywheel/clutch
will replacing the flywheel with a lightweight street/racing flywheel (approx 11-12 lbs) and the clutch with a street/racing clutch help in performance? will i be able to get more hp/torque to the ground? or will i just b able to get it quicker to the ground(meaning pure faster accelration?)

i disagree. a lightened flywheel should result in greater wheel hp (not sure how much, but this was just discussed and dyno'd on one of those speed channel half hour shows on an rsx). it doesn't enhance the motor's output obviously, but is has less inirtial drag on the drivetrain, thus resulting in less of a driveline hp loss.
Here's a quote from and older post:
Yes, less load on the engine therefore less drag during the rev. Disadvantage is poor acceleration out of the hole for a launch, ie Drag racing. You need the inertia of the heavy flywheel because we lack torque, and since you don't produce much boost from a standing start, maybe 4 or 5 psi, the inertia from the flywheel spinning at high rpm helps to keep the engine from bogging out of the hole. The benefit on a road course is the flywheel is light and since you are slowing and accelerating rapidly the engine can recover the power faster if it doesn't have to work as hard to spin the flywheel to get the power to the ground!
