A tire shop should be able to check the tie rod ends and ball joints to see if they need to be replaced. It would be a good idea to closely examine the front a-arm on the side of the collision. If the a-arm is bent, the alignment will be compromised. If you have been driving the car much with the problem you describe, you will likely need new tires as well. The irregular wear produced by the alignment issue will probably cause the car to pull or shake even when the alignment is corrected.
