if it's blue loctite then you should be able to just remove them as normal.
if it's red loctite then you'll need to apply heat to the bolt, easiest way is to put a slodering iron on the blot head, as long as the bolt is not in plastic.
you can take apart the diffs, lightly sand down the edge where the gasket sits, refill and install new gaskets.
it's been so long since i stripped a bolt, if you can find one small enough an
"easy out" may work.
toe is something that the hinge pin bushings control, so you're probably fine there. camber, get a camber gauge, they are cheap and make camber changes easy.
