"You'll be reminded of a poor repair long after you've forgotten how much you saved."
Boy howdy that sure is a powerfully correct statement!
Judith, if you are a local PCA member you can always contact them and ask if someone in the chapter can help you by putting a spare wheel and tire on your car to see if it's just the wheel or more damage exists. Porsche focused body shops may have an extra factory rim lying around too.
If you were in Houston, I'd surely be glad to pop one of my spare track rims on your car to see the full extent of the damage. Wobbly driving is a sure sign of a bent rim.
Visually determining if you bent a control arm is not nearly as easy to determine. They almost have to be removed and compared to a new one to see any difference when the bend is slight:
