Brake Disc Pads problems of the 2005 Lexus RX330

Condensation in the headlights started early on and is only getting worse on my 2005 RX 330. Also, I have already had to switch the front brake pads out and now have to switch the rear brake pads out as well as they started to squeal and the rotors were already resurfaced before. The car doesn't fully brake until I press down extremely hard on the brakes and even then it slightly rolls forward and then stops. Also, when I attempt to accelerate, there is a delayed acceleration. It takes at least 2 seconds before it actually begins to accelerate and even then it is not a instant acceleration but a slow one.
