Regarding point 1, as long as your not sleeping with your head under a window, it's fine.
You can put something between the bed and door, but it has to be solid and cannot be moved around. Or, you can put an indoor curtain up and try to essentially split your bedroom in two, only opening the side that's not directly in front of the bed.
It's all fun and games until someone drops a 7/4 and you don't know which country they're from
