One thing you can do to see if it tracks straight is to run it through a puddle and then drive straight on dry pavement. Make sure it leaves just two tire tracks. I would definitely get a printout of the alignment.

Another thing you should find out is whether they used OEM parts. If you took it to a dealer autobody that is all they should use but a non-Ford shop may have tried to save money (that is, pad their pocket) using non-OEM parts. Ask for proof or look for part numbers if there is any doubt.
I got rear-ended in my '06 at about 3k miles and the insurance tried to cut corners. They told me that a 1 year-old vehicle with 10k miles or more and all they pay for is aftermarket.

Hopefully it is good as new for you.
