Urien Rakarth's Master of Pain special rule affects all friendly units within 12" of him, not just his own unit.
Independent characters can join other units. They cannot, however, join units that contain vehicles or Monstrous Creatures. They can join other Independent Characters, though, to form a powerful multi-character unit! Independent Characters pass Look Out, Sir rolls on a 2+. A unit that contains one or more Independent Characters does not need a double 1 to Regroup if reduced to below 25% of its starting numbres, but instead tests as if it had at least 25% remaining. Full details in BRB. Rule too long to copy verbatim.
A unit that contains at least one model with this special rule ignores the effects of Night Fighting.
Turn 1 None 2 Fearless 3 Fear, Fearless 4 Fear, Fearless, It Will Not Die 5 Fear, It Will Not Die, Zealot 6+ Eternal Warrior, Fear, It Will Not Die, Zealot
The model and his unit treat the current turn as being one higher than it actually is when determining what special rules they benefit from as the result of the Power from Pain special rule. This is cumulative with the Agonising and/or Architect of Agony special rules.
