Edge of the screen? Do you mean the player's screen or the map?

if(bullet_obj.x == maxx || bullet_obj.y == maxy)

You'll have to be more specific.

One way would be to check the direction, then it's location. if(src.dir == EAST && src.x = maxx) etc. etc. You'd have to set one up for every direction, but that's the best way I know.

Just check to see if the location it's moving to is null.

I believe get_step() will return null if the next step would be off the map. Just put in a reference to the bullet, and the direction it's travelling in.
