Hopefully it won't be like the first major extinction event where the planet is bombarded by hard radiation. Then again, we have a stronger atmosphere currently than we did back then.
It won't be. We're 800 light years away and we're pretty sure we're off the dangerous axis. Type II Supernovae are not quite so scary at this distance.
After all, we don't have a convenient tractor beam technology, or any kind of anti-gravity really, to hand-wave that little problem. We're talking about a *lot* of mass here. You wouldn't want it slipping its leash.
If we can build a decent space manufacturing facility then it's easy, actually. Gravity is a great tether and you don't need much mass to tug things around if they can produce impulse. It's sort of shocking how easy it is to influence even large objects when you do the math (and the math for 2 body problems is not that hard).
We already have plans to do this for earth-destroying asteroids.
