Cluth is making a chirping sound

I have 2002 Lexus IS300. When I let the cluth completely out it makes a chirping sound, but if I just barely push on it, it goes away. What is causing this? Also, the steering seems to be messed up. It feels like the car is just pulling in both directions. If I hit a bump, it feels like the car just takes off to one direction. The weird thing is, it will do it both to the right and left. What could this be?
