The radio could be either a fuse or a loose connection.
The noise during cornering could be air in the power steering system.
Unless the mechanic fiddled with stuff he shouldn't have during the starter change, it should not be able to cause any of the problems you mentioned. The one exception is if he installed the starter incorrectly and it isn't properly aligned, the flexplate and starter gears could be hitting each other.
