The stem bolt is probably easier to deal with. When I see these, I find a screwdriver just slightly wider than the long diagonal of the hex hole, and tap it in with a hammer so it cuts it's own slot. Then holding the blade with good pliers (or a wrench if it has the convenient hex at the handle) use i to turn the bolt as if it were a big screw. (This generally destroys the bolt and so precludes reuse, but in some cases you can get away using it as long as the slot holds up)
Another way is to use something like JB Weld to sort of glue the key in. Pack the head and press the key fully to the bottom, forcing out excess. (tap the key home with a hammer). Allow 48 hours for it to cure, and the bolt should come out.
Last ditch if all else fails and you've decided the stem is toast anyway. Cut the stem through below the extension, tap down the expander bolt shaft and use pliers to work the remaining stub out. Do not cut close to the headset, you want enough to hold and pull up. As I said, this is strictly a last resort.
The brake may be easier. Check the threads, then reassemble without th cable and see of the nut can close up to and at least halfway across the hole. If not use a washer. The nut or washer must close far enough to bear on and bend the wire as it leaves both sides of the hole. If your brakes are of the kind that holds the cable to the side of the anchor bolt, it's similar logic. You need good threads and a rigid washer to securely trap the wire so it can't slip.
BTW- most of these bolts are still available, but there are various sizes so bring yours to a bike shop for a match.
