Well, the vibration only happens in 1st gear when i take off now but when i gas it a little bit like at 3k rpm the vibration almost gone. But, since i've only done 150 miles so far on the new clutch, things are pretty much getting better. Is it because the clutch hasn't been broken in yet? Because every day now i feel the take off is improving (less vibration). About the noise, I had the hood open while my friend start up the car, the noise was coming from the belts!! It squeaks for few seconds and it goes away! I replaced all belts about 3k miles ago!!
