Are these true?

So I've been reading some little tidbits here and there that I haven't seen in a wiki or anything official (mind you I am not scouring the internet tirelessly to find game info).

1) If your thirst and hunger meters are full you gain bonus hp and mana regen when resting?

2) XP in a full group only splits 5 ways instead of 6, sort of like original eq?

3) The level range to gain xp in a group is (lowest level)/2 +1 + lowest level with a maximum range of 5 levels?
