some questions (Gothic 2)

who is not difficult, explain to the beginner :
1. whether praying to Beliar to get the gold, giving this part of the maximum life?
2. is there a way to get into the Minental even in the beginning of the game - jumping from the tower of Xardas to the rock.
if you manage to get to the castle and talk to Garendon first visit Horinisa - how to behave in the game, as it appears to further the plot?
