You are looking for a front end alignment and you want the best alignment you can get . This information is very crucial to your satisfaction . My advice is to get a front end check , suspension check and tire check first because often what we find that is going on with vehicles is that one of these items is faulty and causing what you think is an un-aligned condition . Yes with our potholes and rough roads the vehicle can be out of alignment so yes get yearly alignments to keep your tires from wearing but beware that if you have a shaking or pulling it may still be there when you are done getting an alignment and it will be no fault of the alignment process .
