Add Steering Wheel to main screen

I’m brand new to Unity3D, so I apologize in advance if my question shows my lack of knowledge/experience.

I’m making a racing game from a Tutorial, and I’m trying to extend the project a bit. I’d like to add a steering wheel to the main view, always at the bottom of the screen (regardless of where the camera points or where the car is), that turns to show the user how his controls are affecting his steering. However, I can’t figure out a way to do this.

I also created a textual speedometer, which I’d always like to appear in the bottom right hand corner of the screen, regardless of the movement of the car or camera. I’ve only succeeded in attaching it to the car, so it swings around then the car turns (which adds a neat affect, but it isn’t the desired behavior).

Any advice, suggestions, or pointers are greatly appreciated!
