Hard to tell what part u need unless looking at the car, but if your wheel riped of you will most likely need new tie rods(inner and outter), lower control arm w/ball joint, possible new bearing. You most likely will need new CV joint and CV boot. You probably damaged you brake rotor if your wheel completely fell off while driving. Now i may be wrong, but if you do need parts, try local scrap yards and try to get full assembely pieces. Keep in mind if you see any Eagle Talons of the same year, they have the same parts but will probably run you cheaper. Oh yea, i would suggest buying new tie rods for both sides if you have the budget, cause having new tie rods on one side and old on the other is not to good, but you can still get by.
