About fruit re-spawining.It is officially stated by Oda that they do respawn. In the SBS of either volume 21,43 or 48 (the ones i have) Oda implies it. XD

I awlays thoiught it was the Gomu Gomu no mi, but nevertheless, if it was, im sure at least ONE guy in the series as of yet would have noticed it out (especially the marines)
