what is the difference from a Ultrasonic Range Finder and a Infrared Sensor? and witch one do i use so my robot wont run into the wall or something in his way?

Both will detect objects in the way.
IR is cheap, and good for most applications, ultrasound is expensive, and can usually detect longer distances, IR is perfect for starting, I never felt the need for ultrasound.
And oh, good IR sensors don't get affected by sunlight.

There is an excellent tutorial by airman00 which compared Infrared and Ultrasonic Sensors.
You can find it under the members section of SoR.
