1.I believe Communion and Power Of The Spheres will increase holy level. This can be usefull in a number of cases.

2.Communions are necesary normally to make these guys stack up. Also, they can summon mages that are good, and can cast some nasty multi-path spells.

3.Not so much.

4.Does you nation start out with a unit that has a path in blood? If so, then AFTER you get Sanguine Rods, then blood hunting can work. Since you often do this instead of gold income(set tax rate to zero to reduce unrest) this means you can have less order, or even disorder. Which makes the Luck scale more powerfull. That said, you will need something to stop other players from killing you in the early game.
