Sounds a bit high. Get them to break out the alignment and see where the costs are. It's not a difficult job but it's not something you can do in 1 hour either. I'd say that a shop that knows the car should be about to do it in a couple hours so $200-$300 is more than fair.
Though there is some debate whether springs actually "settle", conventional wisdom is that you should probably wait a few days or week to have it aligned anyway.
