I think you're right on the second point (I haven't read the IEEE spec lately, just looked at wikipedia), and wrong on the first. IEEE fp definitely allows for positive and negative zero, so the emulator should be generating them when the spec calls for them to do so. I hope we will soon be emulating vfp floating point instead of the old arm7500 architecture.
