Do you have any tire wear issues or experience any pull to either side at all? If none do not even bother.

However, you can do a quick check as SoCal had mentioned if you have a level ground or driveway.
The only alignment check you can really do is the toe-in and toe-out on both front and rear tires. I do this by having two 48" aluminum straight ruler, a tape measure and a friend to hold the other ruler. Lock your steering wheel. Place each straight edge ruler on the bottom third section of each front tires parallel to the ground making sure they are centered on the tires. Measure the front distance and rear distance between the straight ruler ends by passing the tape measure under the car. Same measurement means zero toe angle. Rear distance greater than front distance means toe-in and vice versa toe-out. Same applies to rear tires. Going back to your geometry, you can calculate the toe angle.
Camber check can be done with a straight edge and an angle finder you can buy from Home Depot carpentry section. Make sure straight edge is as long as the rim diameter. Place straight edge touching the rim vertically. Check camber with the angle finder. Caster is tricky.

That's all you really can do. If you are brave enough, you can make the adjustments yourself. Good luck.
