Vibration and brake knocking

So i put this lift kit on my yj http://www.jeep4x4center.com/jeep-li...s-lift-kit.htm

and some 33" tires. After i put on the lift kit and took it for a drive it had these massive vibrations that started at around 45 mph. I thought my wheels needed to be realigned so i took the jeep in to get the wheels aligned. When i drove it after they were aligned the vibrations werent quite as bad and now it only vibrates bad when i let off of the gas in 4th and 5th gear. When i accelerate it doesnt really vibrate much. There is also now this knocking noise on the brakes when i press them at low speeds (like under 20 mph.) When im running faster and press them it doesnt make the noise though. Can anybody help me out on anything here

also im running a stock driveshaft
