They're fairly easy to get from a fasteners place, just find out in the PET parts catalogue the dimensions of those bolts, and replace them using antiseize and the proper torque. The one going into the chassis takes over 100 ft lbs so make sure the bolt is the proper grade for that torque (10.9 i think they need to be?). Then to be sure get the alignment checked, don't buy an alignment just ask a shop with an alignment rack to set it up on the lift so you can see what the current angles are and if they're all within specification, they shouldn't technically charge just to check alignment, but they might charge a small fee.

That 3 pin connector is just a diagnostic port intended for an RPM feedback signal, there is a rubber plug that covers it.
