My simple rule? If you can't see them, they qualify as invisible.
That's it. So if someone successfully hides, and you don't make a successful spot check, they're invisible.
If you're blind, all your foes are invisible.
etc etc.
Makes things a lot easier.
Oh, and you can't get full cover/concealment against someone without moving at least 5' - because if you could make an attack, they have line of sight to the square you occupy, and you to them. It doesn't matter how you maneuver or scrunch up, unless you actually move.
